The following photographs were taken at Phoenix Deer Valley Airport (DVT) Phoenix,Arizona on 04-01-2001 and show a Canadair CL.215 water bomber,registered with Canadian marks C-GHVX on 19-01-2001 to Bombadier Inc,North Bay,Ontario,the serial is Greek Air Force 2055 which is also its manufacturing serial number,this aircraft was originally built as series 215-811 but has now been modified to turboprop configuration,the plate near the tail states a model CL.415,at the time that the photograph was taken she was on her way back to Greece.
The CL.415 Water bomber is powered with two Pratt & Whitney Canada PW123AF Turboprops which give a cruise speed of 240 mph,this magnificent machine is in service throughout the world with fire fighting organisations,a world beater the aircraft originally appeared with Pratt & Whitney R-2800-C-A3 radial piston engines,the design can be retrofitted with the newer turboprops.
The type made its first flight back on 23rd October 1967 and made its first water take offs in 1968 with full certification being obtained for Canada & the U.S.A during 1969.
A total of 112 aircraft had been delivered up until March 1989 going to the governments of France,Italy,Spain,Thailand,Venezuala,Yugoslavia,a nd 8 Canadian provinces,the aircraft can scoop up salt or fresh water via scoops positioned underneath the machine,or ground loading at airports where retardents such as borate is added with a capacity of 1,412 U.S Gallons,the aircraft have also been used to drop foam onto oil fires using a foam injection device fitted on board.
Patrol and rescue are also ideal roles for this type of aircraft and she can be configured for flight engineer,navigator and two observers in this role.
The Turboprop version was announced in August 1986 and became available as a retrofit for the many delighted operators during 1990,44 per cent of sales revolve around firefighting and aerial spraying,the other sector being maritime,military or surveillance tasks.
Ferry range with a 1,950 lb payload is 1,295 miles,a true workhorse serving the nations of the world.
Note the enormous endplate fins on the winglets,a feature of the CL.215T these direct eddy currents upwards and away from the airframe.
Just visible are the huge and effective fowler flaps which give a stall speed of 88 mph at a 15 degree setting.
The well sealed undercarriage units which fold neatly into the fuselage sides.
The huge water tanks can be filled in ten minutes whilst skimming the water at 81 mph.
Mooring connector and the specially strengthened hull sections are evident in this view.
Superb engineering is the keynote of of the CL.215 a machine built to withstand harsh operating conditions,the high standards of sealed rivetting are evident here..
The new winglets on the CL.215T also produce additional lift as well as serving airflow deflection,this one is a tough bird to withstand low level buffeting and speedy retardent delivery.

The Bob Hoover story
After his Spitfire was shot down by a Focke-Wulf 190 over the Mediterranean in 1944, Hoover was captured and spent 16 months in the Stalag Luft 1 prison in Barth, Germany. He eventually escaped, managed to steal a Fw 190 (which, of course, he had never piloted) and flew to safety in Holland. After the war Hoover signed up to serve as an Army Air Forces test pilot, flying captured German and Japanese aircraft. He became buddies with Chuck Yeager; Hoover was Yeager's backup pilot in the Bell X-1 program, and he flew chase in a Lockheed P-80 when Yeager first exceeded Mach 1.
Hoover moved on to North American Aviation, where he test-flew the T-28 Trojan, FJ-2 Fury, AJ-1 Savage, F-86 Sabre, and F-100 Super Sabre, and in the mid-1950's he began flying North American aircraft, both civil and military, at airshows. Jimmy Doolittle called Hoover "the greatest stick-and-rudder man who ever lived."
Hoover is best known for the "energy management" routine he flew in a Shrike Commander, a twin-engine business aircraft. This fluid demonstration ends with Hoover shutting down both engines and executing a loop and an eight-point hesitation slow roll as he heads back to the runway. He touches down on one tyre, then the other, and coasts precisely to the runway center.
Despite the numerous awards accorded him, Hoover remains humble enough to laugh at himself. He notes in his autobiography, Forever Flying , that in the 1950's, after showing off his Bugatti racer to the neighborhood kids, he asked, "Well, what do you think?" One youngster's reply: "I think you've got the biggest nose I've ever seen."

Bell Airacobra

The XP-59A Airacobra was the first American turbojet-driven fighter which developed in the greatest secrecy during WWII,even to the extent of fixing a dummy airscrew on the nose whilst on the ground. In April of 1941, U.S. Army Major-General, Henry "Hap" Arnold had a trip as an emissary to Great Britain. He was shown the British top-secret first jet aircraft, the Gloster E-28/39 prototype. General Arnold was so impressed by this new technology and asked for the engine blueprints to start the American own design. After his return in United States, he selected General Electric to build the jet-engines; Bell Aircraft Corp was chosen for the airframe design because of its location which was near the General Electric plants. Only 13 months later, the first U.S. jet-powered prototype, XP-59A took its first flight into the air in October 1942. After a year of test and evaluation, the P-59 was ordered into production. However, it never got into combat during the war but provided valuable flight data for the process of the next American jet fighter, the Lockheed P-80 Shooting Star.

AUSTER B.4 AMBULANCE FREIGHTER.
Auster B.4 Ambulance Freighter.
Plans were published by the Aeromodeller magazine as a free flight subject,status of availability not known ?.
The Auster B.4 Ambulance Freighter was a one off design manufactured as a contender for a rough field operational light aircraft, with the ability to carry small payloads,the entire rear portion of the pod portion of the fuselage could be removed to accomodate a field stretcher or even small motor cycles,this aircraft was shown in prototype form at the annual S.B.A.C show at Farnborough attracting a lot of interest but alas no orders.The aircraft was eventually withdrawn from use and stored at Bourton on the Wolds an Auster storage dept near Wymeswold.
It had long been thought that this aircraft had been scrapped with the demise of the Beagle aircraft company who had taken over the Auster company,however this is not so as the aircraft was saved and awaits rebuilding at Carr Farm,Newarke by Mr Cliff Baker.

Details of the PZL-Mielec M-28 Bryza 1
The PZL-Mielec M-28 Bryza 1 is a Polish built licence version of the Antonov AN-28 twin tureboprop transport.
Looking back to its origins,do you recall the Russian Antonov AN-14 twin finned high wing transport aircraft ( Nato code name 'Clod') which first flew in 1958,as a replacement for the Antonov An-2 Colt ?
The piston engined AN-14 was later developed into a more powerful and larger design,the AN-28 ( Nato code name 'Cash' ) which had twin turboprops and first flew in 1969.
In due course the production of the AN-28 was transferred to Poland at the PZL factory,and re-desgnated as the PZL-Mielec M-28,Both civil and military variants were built by PZL-Mielec.
The Polish Navy ordered a small number of the M-28 Bryza in two versions-M-28TD Bryza-1 which is the transport version,and M-28RM Bryza-1R a Maritime patrol and rescue cp-ordination machine.
Engines are two 945 SHP PZL-TWD-108 Turboprops.
Wingspan 72 feet.
Length 43 feet.
Height 16 feet 1 inch.
The M-28RM Bryza-1R ( Maritime /rescue version ) has an under fuselage radome and two clamshell cargo doors.
The M-28TD Bryza-1 has a sliding rear ramp instead of clamshell doors and lacks the radome.

Howard Hughes 'Spruce Goose' flying boat.
1942, the United States announced the construction of `the boat which it flies' and with the approach of Henry. J . Kayzer who was called the shipbuilding king a magnificent chance for Howard Hughes to show the world how his empire reigned and to beat the competition.
Receiving this message Hughes was not to be outbid instead he conceived the Hughes HK-1, the fuselage was to be larger than some aircraft which existed at that time (6 times in fact than the largest ones) the HK-1 which is the largest seaplane in mankinds history built from the conception of an eccentric genius .
This flying boat was made with the lumber which is spruce,now a rare commodity in the Western world hence she was called the " Spruce Goose ".
The eight engines were R-4360 a product of Pratt's & Whitney,Hughes waited patiently for these pristine special builds to appear at the enormous factory that had been set aside, War dominated the development of the HK.-1 and Hughes always knew that if she flew well that they would be interested, the HK-1 would have gone to war had its future had not been terminated by Hughes,a contract from the American government would have made good sense had it not been for the aircrafts marginal and somewhat ungainly performance, but the development was undertaken at great personal expense to Mr Hughes and his enormous empire.
On November 2nd of 1947 after numerous delays and setbacks the Spruce Goose taxied in Long Beach, but as for the enormous boat seaplane flight was officially prohibited by the authorities already as if saying that it did not have strategic value.
But as we all know Hughes fooled the authorities and after a very long take off run she slowly lifted from the water and flew for 1.6 km,it is said that Hughes had made his mind up then that she was not the machine that he had wanted in terms of performance,he cut his losses in so much as further development was not necessary.
It was last flight the giant of vision first, but he had became the United States hero with an air of mystery and enigma.

Ward Elf.
Currently at Breighton airfield are two unusual homebuilts which were oth built by one aeromodeller as full sized aeroplane projects,the one shown here is the Ward Elf a lovely little biplane,whilst in the same hangar is the Ward Gnome.
The Gnome was built in a tiny shed from ordinary commercial materials with lots of balsa wood blocks to get the shape right,she was flown for a brief period by the designer without registration from private property during 1966 in the Lincolnshire/Wigsley area,the problem was that no inspection was made during the construction of the machine and Mr Ward had a problem getting his aeroplane certified,however the aircraft was then sold to gain funds to build the Elf, and the CAA gave way after an extensive inspection of the airframe and registered her as G-AXEI.
The Elf was a follow on using similar techniques to the Gnome except this time it was certified as a ULA type of aircraft and given a microlight registration.
Both machines represent the imagination and expertise of the amateur builder,in this case with a unique minima approach,inspection reveals a very high standard of build.
If these had been made in France or America then they would have been allowed to fly.
Specs of the Ward Gnome were-
Span 15 feet. ( smaller than some current quarter scale flying models )
Length 11 feet 6 inches.
Tare Weight 210 lbs.
All up weight:380 lbs.
Cruise 50 m.p.h.
Range 50 miles.
The original power was a two cylinder Douglas motor cycle engine which gave 14 h.p.

HAWKER TYPHOON
Whilst the Spitfire had all of the glory attached to it there was another equally good aircraft designed and built alongside it for the war effort,the machine was the Hawker Hurricane,designed by Sir Sidney Camm.
Camm was born in 1893 in Windsor. He developed an early interest in aviation and, when old enough, joined the Windsor Model Aeroplane Club where he excelled in building large A-frame pushers covered in oiled silk and powered with rubber motors. In 1912, he and others in the club, made a glider that could carry a man. Just a few years later, aircraft were used in world war one still crude machines but ones that were improving all the time.
In 1925, Camm joined the Hawker Company as a designer. Based at Kingston-on-Thames in Surrey during this time he designed a tiny biplane called the Cygnet that was entered in the Lypme aeroplane trials for low powered lightweight aircraft,this machine is now on display in the museum at R.A.F Hendon, the firm was to produce some of the most famous aircraft in world war two the Hurricane, Typhoon and Tempest being the most celebrated. In the early 1930’s, many still put their faith in biplanes but Camm became convinced that monoplanes were the future and he worked on this idea regardless of what others thought,he was well known for not suffering fools lightly and was a very hard worker.
Camm had a simple philosophy with regards to aircraft design. His first belief was to actually know what was required – to have an obvious target to aim for. He also believed that a design company had to work closely with its engine company so that the airframe and engine married together perfectly and there were no further problems. Camm also believed in keeping things simple in design and also not to stray outside of the knowledge or expertise that he and his team had. He believed that the best designs would always come from using the quality of his design team, and primarily himself, and that untried theories etc would take him away from this belief.
Those who worked with Camm remembered him as a driven man. He became Hawker's chief designer and gained a reputation for detail.The success of some of his aircraft is legendary, primarily the Hurricane that shot down more aircraft than any other in World War Two. The Typhoon had a devastating impact as a low-level attack aircraft flying at zero feet straffing German railway installations during daylight.

January 1918 a competition open to single-seater fighters powered by the 160 hp Mercedes engine was held at Johannisthal, near Berlin. It was won outright by an angular little biplane with thick cantilever wings, the Fokker D.VII, designed by Reinhold Platz. Unquestionably the best all-round German fighter of the First World War, it was a development of Platz's experimental V.II, built late in 1917.
Its engine was either the 160/180 hp Mercedes or the 185 hp BMW, neatly cowled and fitted with a frontal radiator. BMW D.VIIs had the better performance and were much sought after. The 200 hp Benz was experimentally fitted without great success. The exhaust system was either the usual external horizontal pipe on the starboard side, or separate internal pipes connected to a large main pipe which protruded through the starboard cowling.
D.VII wings had two spars with plywood ribs; the leading-edges were of ply, the rest of the structure fabric covered. Unequal chord ailerons framed in steel tubing, were fitted to the upper wing only, which had a slight curved cutout in its trailing-edge. The lower wing was housed in a recess in the fuselage bottom; both planes had wire trailing-edges, giving *em a 'scalloped' appearance. Interplane and center section struts were of streamlined steel tubing.
The fuselage was constructed of wire-braced welded steel tubing with a three-ply top decking behind the cockpit; the whole being fabric-covered, except for the engine cowlings. Fin, balanced rudder, tailplane and balanced elevators were also of fabric-covered steel tube. Two struts braced the tailplane from below. The undercarriage was of streamlined steel tube and its axle was enclosed in a large fairing which gave some extra lift.
Following its success at Johannisthal, the type was ordered in large quantities; not only was it built by the Fokker concern (Fok. D.VII F), but also by its rivals, the Albatros Werke (Fok. D.VII (Alb.)) and the Ostdeutsche Albatros Werke (Fok. D.VII (OAW)). Mercedes and BMW engines appear to have been distributed impartially to all three companies.
While not especially fast, the D.VII's strong point was its great maneuverability at high altitudes. It was extremely easy to fly and had no terrors for the beginner. Jagdgeschwader Nr. 1, the Richthofen 'Circus', received the first D.VIIs in time for the Second Battle of the Aisne in May 1918, and soon found that the new type gave them a good margin of advantage over their opponents. By the autumn the majority of the Jastas had been reequipped with D.VIIs. So highly did the Allies esteem the machine that their Armistice terms specifically ordered the surrender of all Fokker D.VIIs.
As a safeguard against a possible shortage of steel tubing and competent welders, the Albatros company built a D.VII with a plywood fuselage, but it was not found necessary to produce this variant. When the war ended, production of the type for Austro-Hungary had begun at the Hungarian Engineering Factory, Budapest (MAG).
Paul Mantz rebuilt this Fokker D.7 part of his large collection of flyable WW.2 replicas.
The colourscheme is red and black.
Delightful little rubber driven flying model of the Fokker D.7.

As a model subject the Sopwith Pup is ideal,with its generous wing area and tail surfaces there is very little to go wrong in the aerodynamics department,the large cowling will adequately hide even the most awkward of glo motors,but why not go for a nice lightweight electric model ? there is plenty of room to fit a decent battery box coupled with easy access,the short nose will require sensible ballast up front anyway so why not use the battery set well forward ? the undercambered wing section is not necessary,a flattened clark Y will suffice nicely,the centre section struts could carry a built in centre section to which the pre rigged wings could be located,or if you like a one piece wing arrangement then make it bolt onto the centre section itself.The dual ailerons are linked with simple pushrods,they are powerful and require only a smal amount of movement,the fuselage is a basic box with stringers on the top,the tailplane can be a flat plate built up lightweight structure,the aeroplane looks right and has a nice sit in the air,overall an ideal model subject that has lots of period character.

ML UTILITY AIRCRAFT.
In 1955 ML Aviation at White Waltham designed and produced a portable flying machine called the ML Utility ML.1 given the serial number XK776,the aircraft featured an inflatable rubberised fabric wing and quick release fittings enabling the aircraft to be rigged and de-rigged fairly quickly.
Despite evaluation by the British Army Air Corps at Middle Wallop further production was not taken up,the flight characteristics were unusually slow and the machine was then stored until saved by the Army Air Corps museum.
With the advent of the lightweight helicopter perhaps the practability of the ML design were outweighed,however the company continues to produce many ancillary products for the aviation industry.

TIPSY TRAINER.
Avions Tipsy in Belgium,and Tipsy company Ltd in the UK were companies that were established in the 1930's to build unique light aircraft which were designed by the brilliant designer E.O.Tips,these were formerly manufactured by Avions Fairey.
The aircraft were only built in very small numbers,designated the Tipsy S.2 single seater monoplane,the B & B2 monoplanes seating two in a side by side open cockpit,and the Tipsy M,a monoplane trainer with tandem cockpits beneath a continuous transparent canopy,this was powered by a Gipsy Major powerplant.
Tipsy Trainer 1 G-AFSC operated by the Armstrong Siddeley flying club at Baginton during the fifties and mid sixties.
After World War 2 Avions Fairey attempted to manufacture and re-establish themselves as aircraft constructors,the Tipsy Belfair was a cantiler low wing monoplane of wooden plywood and spruce construction,undercarriage was enclosed in a spatted pant called a speed fairing and the structure was covered in lightweight fabric.The enclosed cabin provided accomodation for two people with a central pass-over type of control column,duplicated rudder pedals made it possible to fly the aircraft from either seat.
Powerplant: one 62 hp Walter Mikron inverted inline piston engine.
Performance:Maximum level speed-110 mph.
Cruising speed-99 mph.
Service ceiling-19,685 feet.
Range-466 miles.
Weights:Empty-540 lbs.
Maximum take off weight-1,102 lbs.
Dimensions:Wingspan-31 feet 2 inches.
Length-21 feet 8 inches.
Height-5 feet,7 inches.
Wing area-129.17 square feet.
As a model subject the little Tipsy monoplanes would make excellent subjects,the boxy fuselage with stringered upper decking coupled with a delightful wing platform would ensure a steady flying model,be careful not to ower power her as the original was fitted with a small economical powerplant that was adequate for the tasks of training and cross country flying.The wing slots are best left sealed as they can present aerodynamic problems to such a small scale,the cantilever undercarriage would be best sprung aft where it fits the wingspar with a small slot underneath the wing to avoid damage to the structure.
An inverted four-stroke neatly cowled would fit the bill nicely.

ZENAIR CH 620 GEMINI.
The Zenair 620 Gemini is the only twin engined kit aircraft available today,this lovely little twin gives 150 m.p.h in the cruise and is fitted with twin 80 h.p Jabiru engines,offered with either tricycle or taildragger undercarriage.
If you want to build one then the all in kit will cost you $19,995.00 ex factory.
Just look at the lines of this aircraft,she is just asking to be modelled,the attractive layout offers plenty of dihedral for stability,high set engines which will give for less than smooth runway operation,a sturdy undercarriage and a really sleek tail,mount two fourstrokes sidewinder and you have an ideal scale sports model.
This view shows the neat undercarriage retraction system,wheels just protude in case of emergency landing to avoid tripping over,the faired tailwheel is an optional extra.

CUSTER CHANNEL WING.
This unusual aircraft has engines and scooped out portions on the wings to help it in the vertical climb. The idea behind the aircraft was to take off straight up in the sky. Willard R. Custer in known as the father of STOL (Short Take Off and Landing) aircraft. Willard R. Custer worked for nearly 40 years to see Custer Channel Wing Corporation's serial #1 CCW-5 (5 for five passenger) become a reality. Unfortunately, lack of financial support prevented further development of the concept, and only CCW-5, awaiting restoration at the Mid Atlantic Air Museum, and CCW-2, at the Smithsonian National Air & Space Museum's Paul Garber facility, survived.
Custer's approach was based on the idea that it is the speed of the air over the wing, and not the wing through the air, which generates lift. In the channel wing, air pulled through the wing by the props combined with forward motion generated double that of standard wing design, giving the aircraft very short takeoff and landing roll.
Unfortunately the idea never took off.
The brainchild of Willard Custer, the channel wing aircraft, of which this is the first, provided capabilities by forcing airflow over the wing channels. The arrangement was quite effective at low speeds, but high speed performance suffered.
Willard Custer conceived channel-wing aircraft as result of seeing the roof lifted off a barn during a high wind and carried a few hundred feet into a nearby field. Reasoned that wind created a negative pressure differential which produced a lifting force greater than weight of roof and forces holding it in place; concluded that high speed air moving over suitably shaped airfoil could produce similar effect. To determine most efficient airfoil, began experimenting by blowing air over various shapes. Semi- circular configuration showed greatest promise, decided to build airplane around channel wing design which had produced a static lift force of 8 pounds per engine horsepower; in motion, increased to 13 pounds per horsepower. Concluded that channel wing produced about one-third more lift per sq ft of wing area than conventional airfoil. NASM's CCW-1 was first of 4 channel-wing models eventually built. Initially flew with conventional outboard wing sections in place (as displayed), but were later removed and only channel sections of wings remained. Performance satisfactory even with 1 engine out; motion of air on dead side continued to produce enough lift to maintain control.
Contra-rotating props enhanced lateral stability. Cross shafting between engines considered but never introduced. STOL characteristics excellent; takeoff required as little as 200 feet and plane could land at 36 mph. Prototype of final version, CCW-5, conversion of pusher Baumann Brigadier executive aircraft, flew 13 Jul 53; first production model rolled out 4 Jul 64. Despite remarkable low-speed handling and maneuvering qualities and interest of potential buyers, could not develop resources to go into production. By 1964, Beechcraft Bonanza had captured much business aircraft market and vertical performance of turbine-powered helicopters overshadowed short-field capabilities of channel wing.
Later, Custer claimed the relative engine-to-wing placement on Republic (Fairchild) A-10 infringed on his patents but lost on grounds that both he and Republic had recognized similar airflow (natural) phenomena and incorporated them in their respective designs. Custer, a great grand-nephew of George Armstrong Custer, had been offered as much as $40 million for patents but refused, preferring to stay independent.
Died in 1985 his son, Harold, accumulated over 1,000 hours of channel-wing flying time and continued to work on ultra- light, single-engine, channel-wing design and hoping that the channel- wing principle will reemerge in future aircraft designs.

SOPWITH CAMEL
Sopwith Camel F6394.
The Sopwith Camel was without a doubt the finest British fighter of World War 1,the aircraft was basically a development of the Sopwith Pup with a somewhat heavier and more powerful rotary engine the 130 hp Clerget Rotary piston engine,the Camel had armament,fuel,pilot and powerplant all situated within a short distance,this resulted in outstanding manoeuvrability which was coupled to the torque of the large engine,this made snap turns to starboard which were so fast that pilots used this to good advantage in the air making a total of over 3,000 its total tally of victims.The type was also used as a day or night fighter by British Home Defence units,and the Camel is considered to have played a big role in the in the defeat of the German Gotha bombers.
The name Camel was not the aircrafts official one,being called the Sopwith Biplane F.1 designation of the first production versions.Other engines fitted included the Bentley,Clerget,Gnome and Le Rhone,plus the Gnome Monosoupape.The opwith 2F.1 Camel was designed expressly for shipboard use and remained in service until after World War 1,the final production figure was 5,490 aircraft,they were also used by the air forces of Belgium,Canada,Greece and the American Expeditionary force,and with the Slavo-British Aviation group operating in Russia in 1918.

Royal Aircraft Factory R.E.8
R.E.8
The Royal Aircraft Factory R.E.8 had been designed and developed in 1916 to meet a Royal Flying Corps requirement for an aircraft to undertake a reconnaisance and artillery spotting function,it quickly gained the nickname 'Harry Tate' which was a direct pun on a music hall comedian of those days.
A total of 4,077 examples of the R.E.8 were built and the first such aircraft entered service towards the end on 1916,several were lost in accidents and the type was temporarily withdrawn from use following investigations and rectification procedures were undertaken,during this time the R.E.8 acquired a revised tail fin and rudder to avoid the nasty spinning characteristics with earlier machines in service.
Despite its rather slow flying characteristics and in the absence of a better aircraft the R.E.8 slogged on in the valuable artillery spotting role right on until the Armistice.
Powerplant: 150 hp RAF 4a V-12 piston engine.

Howard DGA.8
Ben Howard designed and built his first aeroplane in 1933,this machine the DGA-1 (standing for Dammed Good Aeroplane) led to the company Howard Aircraft Corporation to be formed in 1937.A series of successful racing aircraft were built DGA-3 Pete,DGA-4 Ike,DGA-5 Mike,then came along the classic DGA-6 Mister Mulligan which was a sleek four seat cabin design which walked away with all three of the American air races during 1935.The DGA-8 shown in the photograph was a commercial design which appeared in 1936,this then developed into the DGA-9,DGA-11,DGA-12 and DGA-15 which had various engine combinations from a 300 hp Jacobs to 450 hp Pratt & Whitney Wasp Junior.
The U.S.Navy used a version called the GH-1,GH-2 and NH-1 instrument trainer,the U.S.Army Air Force impressed a total of 19 aircraft from civil sources for use as light transports and communications machines,these were designated as UC-70's.These trusty and reliable aircraft remained in service for many years.

GRUMMAN DUCK AMPHIBIAN.
Wonwings Grumman Duck gets its first flotation tests,scratch-built from Harold Towner plans and converted to take radio control,despite the tricky fuselage contours she makes for an attractive model subject.
Starting life as the Grumman FF-1 and F2F carrier based fighters for the U.S.Navy,the aircraft had some unique new ideas in its design including a fully retractable undercarriage that went into the sides of the single float.
Grumman was awarded a contract to supply the XJF-1 prototype which first flew on 4th May 1933,following extensive test flying the Navy ordered 27 model JF-1's which were delivered in 1934.
These aircaft replaced the older Loening OL-9 observation and general purpose machines in the observation and general purpose role,the construction was light alloy structure for the wings which were fabric covered,and the fuselage was made from a stressed skin and light alloy structure.
Next came along the Grumman JF-2 aircraft which saw service in the U.S Coast Guard with four transferred to the U.S.Navy later,another version called the J2F-2A equipped the Marine squadron VMS-3 being equipped with machine guns and under wing bomb racks.
The final production aircraft were manufactured in 1940 as the model J2F-5 which were the first aircraft to carry the name Duck officially.
The Duck remained in service throughout the war years operating from carriers and land bases in a variety of roles,these included patrol,photo-survey operations,air sea rescue and target towing.

B.E.2C
Serial 347 History of the aircraft above-

The B.E.2c was a twin seater, tractor biplane with a four bladed propeller. It was powered by a 90 hp RAF 1a motor giving it a maximum speed of 116 mph at 1,980 m, and taking 45 minutes to reach 3,000 metres. It was, however, a radical improvement over it's predecessors with the addition of four ailerons, an enlarged rudder and the arrangement of the wings. These changes resulted in a more stable aircraft, although not a more manoeuverable one. The observer was moved to the rear position and given a machine gun, even though his use of it was greatly restricted as he had to remain seated. Another machine gun was occasionally mounted on the front of the aircraft either over the wing or firing obliquely to avoid the propeller. With a full bomb load of 100 kg the observer had to be left out.

Avro Lancaster.
Avro Lancaster.
The Lancaster flew for the first time on January 9,1941 as a four-engined development of the Avro Manchester. The RAF began to equip with Mk Is in early 1942 and used them first on March 10th against targets in Essen. Altogether, more than 7,300 Lancasters were produced in Britain as Mks I to VII and Canada as Mk Xs, and they dropped more than 608,000 tons of bombs on 156,000 wartime missions. Some Lancasters were still flying with the RAF in the early 1950s as maritime-reconnaissance, photo-reconnaissance and rescue aircraft.
Like all successful aircraft the Lancaster not only looked good but its flying characteristics matched its appearance. It is all the more ironic therefore that the birth of Avro's mighty machine owed so much to failure, the failure of its immediate predecessor, the twin engine Avro Manchester. The Avro 683 evolved almost accidentally as a result of recurrent failure of the insufficiently developed Rolls Royce Vultureengines installed in the Manchester.
The industrial and military organisation needed to build and operate the Lancaster was huge. Six major companies built 7377 aircraft at ten factories on two continents; at the height of production over 1,100,000 men and women were employed working for over 920 companies. More service personnel were involved in flying and maintaining it than any other British aircraft in history.
The Lancaster's operational career is littered with impressive statistics, but it is worth remembering that the average age of the seven-man crew was only 22 years. They endured danger and discomfort and many showed great courage in continuing to fly knowing the odds against survival were high. Bomber Command suffered the highest casualty rate of any branch of the British services in the Second World War.

Avro Ashton
Avro Ashton Mk.1 shown in the photograph above.
Following the trials of the Avro Tudor 8, with a tailwheel landing gear and four Rolls Royce Nene Turbojets in paired engine nacelles,Avro decided to build a tricycle undercarriage version but this did not happen,instead jet research aircraft were required and the Ministry of Supply ordered six examples of the Avro Ashton,these were basically shortened Tudor airframes with thicker metal skinning,all of these aircraft had detail differences and were used for a wide variety of tasks.The first and only Ashton Mk.1 flew in September 1950 and was used at Boscombe Down for high altitude research,the second aircraft the Mk.2 flew in August 1951,this was passed to the National Gas Turbine Establishment as a universal engine test bed and flew with great success fitted with the Rolls Royce Avon,Rolls Royce Conway and the Armstrong Siddeley Sapphire.
The third aircraft of which three Ashton Mk.3 were built,the first flying during 1951 was used by the Radar Research establishment for research into radar bombing,the fourth was used by the Royal Aircraft Establishment later going to Bristol for Bristol Olympus and Orpheus engine testing.
Number five the one and only Ashton 4 was flown in November 1952 was used by the RAE for visual bombing research,and later on de-icing trials on the Sapphire engine.
The final Ashton was another Mk.3 flown in April 1952 for bomb ballistic research with the RAEOrfordness,followed by intake icing tests.

CHRISTMAS BULLET.
William Whitney Christmas was Born in 1865, Christmas attended St. John's Military Academy, the University of Virginia, and George Washington University obtaining Bachelor and Master of Arts degrees and becoming a medical doctor. However, he left his medical practice shortly after the Wright Brother's first flights to pursue his own interest in the new field of aviation.
Dr. Christmas claimed to make his first flight in March of 1908 in a plane of his own design. Furthermore, he claimed that after the vehicle crashed into a tree, he burned it to prevent his design secrets from being stolen. While there is no solid evidence to support this story, Christmas did patent, build, and fly a biplane of his own design in 1909. This aircraft, known as the Red Bird, was representative of many of his later designs and can be distinguished by its anhedral (down-sloping) upper wings and dihedral (up-sloping) lower wings. Another noteworthy tidbit about this design is that it appears to be a virtual copy of a plane built by a company named AEA that was, interestingly enough, also known as the Red Bird. In the words of one historian, "the eccentric Dr. Christmas was not above employing the ideas of others" and may well have patented another company's design!
Nonetheless, the success of the Red Bird and a modified Red Bird II led to the founding of the Christmas Aeroplane Company based in Washington, DC, in 1910. The company became the Durham Christmas Aeroplane Sales & Exhibition Company around 1912 and later the Cantilever Aero Company after moving to Copiague, NY, in 1918.
While few of Christmas' aircraft ever saw production, his most famous and controversial design was the Christmas Bullet shown above.
