29 December 1941: The first North American Aviation XP-51 fighter prototype, Air Corps serial number 41-038, arrived at the National Advisory Committee for Aeronautics Langley Memorial Aeronautical Laboratory, Langley Field, Hampton, Virginia, for flight testing. This airplane was the fourth production Royal Air Force Mustang Mk.I, North American serial number 73-3101.
The test program resulted in an improved aileron design which significantly improved the Mustang’s maneuverability. The new aileron was used on all production models.

41-038 was returned to Wright Field on 2 November 1942. The second XP-51, 41-039, arrived at Langley in March 1943 for continued testing.
The Mustang Mk.I (NAA Model NA-73) was a single-place, single-engine fighter of all metal construction. It was 32 feet, 3 inches (9.830 meters) long with a wingspan of 37 feet, ½-inch (11.290 meters) and overall height of 12 feet, 2½ inches (3.719 meters). The airplane’s empty weight was 6,280 pounds (25,848.6 kilograms) and loaded weight was 8,400 pounds (3,810.2 kilograms).

The Mustang Mk.I/XP-51 was powered by a liquid-cooled, supercharged 1,710.60-cubic-inch-displacement (28.032 liter) Allison Engineering Company V-1710-F3R (V-1710-39) single overhead cam 60° V-12 engine, with a compression ratio of 6.65:1 and a single-stage, single-speed supercharger. This was a right-hand tractor engine (the V-1710 was built in both right-hand and left-hand configurations) which drove a 10 foot, 6 inch (3.200 meter) diameter, three-bladed, Curtiss Electric constant-speed propeller through a 2.00:1 gear reduction.
The V-1710-39 had a Normal Power rating of 880 horsepower at 2,600 r.p.m. at Sea Level; Take Off Power rating of 1,150 horsepower at 3,000 r.p.m. at Sea Level, with 44.5 inches of manifold pressure (1.51 Bar), 5 minute limit; and a War Emergency Power rating of 1,490 horsepower at 3,000 r.p.m., with 56 inches of manifold pressure (1.90 Bar). The V-1710-F3R was 3 feet, ¾ inches (0.934 meters) high, 2 feet, 5-9/32 inches (0.744 meters) wide and 7 feet, 1-5/8 inches (2.175 meters) long. It had a dry weight of 1,310 pounds (594 kilograms).

The XP-51 tested at Wright Field had a maximum speed of 382.0 miles per hour (614.8 kilometers per hour) at 13,000 feet (3,962 meters) at wide open throttle, and cruise speed of 300 miles per hour (483 kilometers per hour).
Below 20,000 feet (6,096 meters), the Mustang was the fastest fighter in the world. The Mk.I was 30 m.p.h. (48 kilometers per hour) faster than its contemporary, the Curtiss P-40 Warhawk, though both used exactly the same engine. Below 15,000 feet (4,572 meters), the Mustang was also 30–35 m.p.h (48–56 km/h) faster than a Supermarine Spitfire, which was equipped with the more powerful Roll-Royce Merlin V-12.
The service ceiling was 30,800 feet (9,388 meters) and range was 750 miles (1,207 kilometers).

Two Mustang Mk.Is, AG348 and AG354, were taken from the first RAF production order and sent to Wright Field for testing by the U.S. Army Air Corps. These airplanes, assigned Air Corps serial numbers 41-038 and 41-039, were designated XP-51. They would be developed into the legendary P-51 Mustang. In production from 1941 to 1945, a total of 16,766 Mustangs of all variants were built.
North American XP-51 41-038 was transferred to the Smithsonian Institution National Air and Space Museum. It was restored in 1976. It is now in the collection of the EAA AirVenture Museum, Oshkosh, Wisconsin. It has a current FAA registration number, N51NA.

The prototype Consolidated XB-24 heavy bomber takes off from Lindbergh Field.
29 December 1939: Consolidated Aircraft Corporation’s chief test pilot, William B. (“Bill”) Wheatley, made the first flight of the XB-24, 39-556, from San Diego Municipal Airport – Lindbergh Field, at San Diego, California. The flight crew included George Newman, co-pilot, and flight engineers Jack Kline and Bob Keith. The flight lasted just 17 minutes.
This airplane (the company designation was Model 32) was the prototype of the B-24 Liberator bomber. The U.S. Army Air Corps had approached Consolidated to set up a second production line for Boeing’s B-17 Flying Fortress four-engine heavy bomber. After looking at Boeing’s Seattle operation, Consolidated’s chief executive, Reuben H. Fleet, told the Air Corps that they could build a better, more modern bomber.

The XB-24 was designed to be operated by a seven man crew. It was 63 feet, 9 inches (19.431 meters) long with a wingspan of 110 feet, 0 inches (33.528 meters), and was 18 feet, 8 inches (5.689 meters) high. The wings used the “Davis Airfoil” that had been used on the Model 31, a prototype flying boat, the XP4Y. The root chord was 14 feet, 0 inches (4.267 meters). Their angle of incidence was 3° 0′, with 3° 26° dihedral. The leading edges were swept aft 3° 30′. The total wing area was 1,048 square feet (97.36 square meters).

The XB-24 was powered by four air-cooled, supercharged 1,829.4-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S3C4-G (R-1830-33) two-row fourteen-cylinder radial engines. These had a normal power rating of 1,100 horsepower at 2,550 r.p.m. to 6,100 feet (1,859 meters) and 1,000 horsepower at 2,700 r.p.m at 14,500 feet. The takeoff/military power rating was 1,200 horsepower at 2,700 r.p.m. to 5,000 feet (1,524 meters). The engines drove three-bladed Curtiss Electric variable-pitch propellers through a 2:1 gear reduction. The R-1830-33 was 4 feet, 0.06 inches (1.221 meters) in diameter and 5 feet, 3.48 inches (1.612 meters) long. It weighed 1,480 pounds (671 kilograms).
Consolidated XB-24 low pass.
The XB-24 had cruise speed of 186 miles per hour (299 kilometers per hour), and a maximum speed of 273 miles per hour (439 kilometers per hour) at 15,000 feet (4,572 meters). The service ceiling was 31,500 feet (9,601 meters). Maximum range was 4,700 miles (4,828 kilometers), or 3,000 miles (7,564 kilometers) with 2,500 pounds (1,134 kilograms) of bombs.
The XB-24 was 38 miles per hour (61 kilometers per hour) slower than the Air Corps specification. A number of changes were made, including replacing the supercharged R-1830-33 engines with turbocharged Pratt & Whitney Twin Wasp TSC4-G (R-1830-41) engines. With the addition of the turbochargers, the R-1830-41s were able to maintain 1,200 horsepower up to 25,000 feet (7,620 meters). The propeller gear reduction ratio remained 2:1. At the same time, the round engine cowlings were changed to an elliptical shape that became a characteristic of the B-24. The modified prototype was redesignated XB-24B. In the new configuration, the bomber was able to reach 310 miles per hour (499 kilometers per hour), just 1 mile per hour under the Army’s requirement.

When the Royal Air Force bought several of the YB-24 pre-production airplanes, the Army Air Corps revised the serial numbers assigned to the B-24s. Though it was the same airplane, the XB-24′s designation was changed to XB-24B, and its serial number from 39-556 to 39-680.
The XB-24B was retained by Consolidated, now the Consolidated-Vultee Aircraft Corporation, and in 1944 further modified as a company transport. The prototype was scrapped at Brookley Field, Mobile, Alabama, 20 June 1946.

18,482 B-24 Liberators—more than any other Allied aircraft type—were built during World War II by Consolidated at San Diego, California and Fort Worth, Texas; by North American Aviation at Dallas, Texas; by Douglas Aircraft at Tulsa, Oklahoma. More than half of the total production was built by the Ford Motor Company at Willow Run. During World War II, the B-24 served in every combat theater. In U.S. Navy service, it was designated PB4Y-1 Privateer. It was faster, had a longer range, and could carry a heavier bomb load than the Boeing B-17, but was thought to be less survivable to combat damage. As the war came to an end, hundreds of brand new B-24s were accepted by the Air Corps, but sent immediately to be scrapped rather than placed in service.
William Ballentine Wheatley, (Photograph courtesy of Neil Corbett, Test and Research Pilots, Flight Test Engineers)
William Ballantine Wheatley was born at Chester, New York, 17 December 1902, the first of three children of William A. Wheatley, a public school superintendent, and Mabel Ballantine Wheatley. He was twice married, first, about 1927, to Esther Leary Wheatley, of Massachussetts. They had two children, Mary and William Thomas Wheatley. His second marriage was to Miss Grace Lenore Ray, 18 April 1935, at Washington, D.C. They would have a son, John, and two daughters, Grace and Charlotte Wheatley.
After two years of college, Wheatley joined the U.S. Army Air Corps as an aviation cadet, 3 March 1925. He trained as a pilot at Brooks Field, Texas, and was commissioned as a 2nd lieutenant, 13 March 1926. On 4 May 1927, Lieutenant Wheatley was assigned to the 118th Observation Squadron, 43rd Division, Air Service, at Hartford, Connecticut, as a pilot and observer. He served in the Air Corps Reserve until 1937.
In 1928, Wheatley went to work for the Pratt & Whitney Aircraft Company as a test pilot. He was an air mail pilot in 1928-1929, and then, in February 1929, he became a test pilot for Reuben H. Fleet’s Consolidated Aircraft Corporation at Buffalo, New York. In 1935, Consolidated moved to its new headquarters at Lindbergh Field, San Diego, California. Wheatley moved with it. He and his family lived in a 3 bedroom home about three miles northeast of the airport. In 1940, his salary as chief test pilot of Consolidated was $50,000 per year.¹
Bill Wheatley was killed when a Royal Air Force Liberator B Mk.II, AL503, crashed into San Diego Bay during its acceptance flight, 2 June 1941. Four other Consolidated employees on board also died.

29 December 1935: Early in the morning, Antoine Marie Jean-Baptiste Roger comte de Saint Exupéry took off from Aéroport de Paris–Le Bourget enroute to Saïgon, Cochin-China, as a participant in the long distance Paris-to-Saïgon “raid,” or air race.
The race was sponsored by the Aéro-Club de France, which had offered a prize of ₣1,200,000 (franc français), approximately £16,000 or $70,000, to the winner, providing the finishing time was less than 90 hours. The distance was estimated at 13,800 miles (22,209 kilometers). Any airplane type could be entered in the race as long as it had an official airworthiness certificate and a flight crew of two, or a single pilot with an autopilot.
Antoine de Saint Exupéry was accompanied by André Prévot as the navigator and flight engineer. The airplane was a red and white Caudron C.630 Simoun, c/n 7042.20. It was registered to Saint Exupéry on 9 April 1935 as F-ANRY, a representation of his name (“ANtoine de Saint ExupéRY”). He had flown the Simoun 8,000 miles (12,875 kilometers) in the eight months he had owned it, “. . .and her engine had not skipped a beat; not a bolt in her had loosened.”
Saint Exupery’s Caudron C.630 Simoun, F-ANRY, prepares to take off at Le Bourget. (Succession de Saint-Exupéry d’Agay via Le Musée de l’Air et de l’Espace)
The Société des Avions Caudron C.630 Simoun was a four-place, single-engine, low-wing monoplane with fixed landing gear. It was built of wood, with the surface of the wings and fuselage covered in plywood sheet then covered with doped fabric. Carefully curved aluminum sheet metal covered the top and bottom of the fuselage. The C.630 was 8,70 meters (28 feet, 6½ inches) long with a wingspan of 10,40 meters (34 feet, 1½ inches) and height of 2,25 meters (7 feet, 4½ inches). The airplane’s gross weight was 1,230 kilograms (2,712 pounds).
The engine was an air-cooled, normally-aspirated 9.500 liter (579.736 cubic-inch-displacement) Renault Bengali 6 Pdi inverted inline six-cylinder overhead-valve (OHV) engine with a compression ratio of 5.75:1. It was rated at 180 cheval vapeur (177.5 horsepower) at 2,200 r.p.m. The left-hand-tractor, direct-drive engine turned a two-bladed, metal Helices Ratier variable-pitch propeller. The propeller could be set to coarse pitch by a mechanic prior to takeoff, then an air bladder mechanism could change it to fine pitch for cruise flight. The Bengali 6Pdi weighed 205 kilograms (452 pounds).
The C.630 had a maximum speed of 310 kilometers per hour (193 miles per hour). The service ceiling was 7,500 meters (24,606 feet) and normal range was 1,260 kilometers (783 miles). Twenty C.630s were built before production changed to the slightly improved C.631.

After taking off at Paris, Saint Exupéry followed the Seine to the valley of the Loire and continued south, crossing the southern coast of France near Marseilles. The fliers had been over the Mediterranean Sea for a short while when they saw fuel leaking from the left wing. Prévot calculated that they had lost 20 gallons (76 liters) of fuel. They turned back and landed at Marignane to repair the leak and refuel before continuing. Saint Exupéry wrote, “I drank a cup of coffee while the time lost hurt like an open wound.”
Once again heading across the Mediterranean toward Tunis, they encountered low clouds and heavy rain which forced them down to just 60 feet (18 meters) over the water. They flew along the coast of Sardinia as the weather improved.
F-ANRY crossed the coast of Africa at Bizerte, Tunisia, and about fifteen minutes later landed to refuel. With two hours of daylight remaining, Saint Exupéry and Prévot took off again, now heading toward Benghazi, Libya. They landed there at 11:00 p.m., local time, and in just twenty minutes the airplane had been refueled and once more, they were airborne.
Flying east after moonset, Saint Exupéry and Prévot were in total darkness. After three hours a faint glow of his navigation lights on the airplane’s wingtips told Saint Exupéry that he had flown into clouds, with visibility measured in just feet.
At a time when there were no navigation aids, pilots had to navigate by their compass, airspeed indicator and clock. Though Saint Exupéry had met with meteorologists to plan his flight, there was no way to update the weather information after takeoff. He had no way of knowing whether an expected tailwind had held, or if it had changed; was his speed across the ground faster or slower than planned? Had the wind blown him right or left of course? Had the atmospheric pressure changed, causing his altimeter to read higher or lower than the airplane actually was? Flying across the emptiness of the Sahara Desert with no landmarks, in total darkness and now just a few feet of visibility, he and Prévot could only guess at their position.
4 hours, 15 minutes after taking off from Benghazi, the C.630 crashed into gently rising terrain at 170 miles per hour (274 kilometers per hour).

The airplane had slid 250 yards across the surface of the plateau and was heavily damaged, but Saint Exupéry and Prévot were unhurt. However, their water was lost. They were left with “. . . a pint of coffee in a battered thermos flask and half a pint of white wine. . . There were some grapes, too, and a single orange.”
Without food or water, Antoine de Saint Exupéry and Andre Prévot wandered across the desert searching for help. They followed mirages, and frequently recrossed their own tracks. They always returned to the wreck of the Simoun. They experienced delusions.
After four days, they were rescued by Bedouin tribesmen.

The location of the crash is uncertain, but is believed to be near Wadi el Natrûn in Egypt, west of the Nile Delta.
Saint Exupéry wrote about the experience in Wind, Sand and Stars, published in 1939. It was the basis for his famous novella, The Little Prince.

28 December 1978: United Airlines Flight 173, A McDonnell Douglas DC-8, N8082U, departed Stapleton International Airport (DEN), Denver, Colorado, enroute to Portland International Airport (PDX), Portland, Oregon. Under the command of Captain Malburn Adair McBroom, the airliner carried 181 passengers and 8 crew members. The planned duration of the flight was 2 hours, 26 minutes. The DC-8 carried 46,700 pounds (21,183 kilograms) of jet fuel, sufficient for the flight plus an additional 1 hour, 5 minutes fuel for the required 45-minute reserve and any contingencies.
On approach to Portland, the crew lowered the DC-8’s landing gear and flaps. They felt a heavy thump followed by a vibration and the airplane yawing. The indicator light showing that the main gear was down and locked did not illuminate.
Concerned that there was a problem with the landing gear, Captain McBroom aborted the landing and put the airliner in a holding pattern south of the airport. For approximately one hour, Captain McBroom, First Officer Roderick Duane Beebe, and Flight Engineer Forrest Ervin Mendenhall attempted to determine the nature of the problem. Finally, though the situation was not resolved, the crew turned toward Portland and prepared for an emergency landing.
At 18:06:46, the flight engineer reported, “We’re going to lose an engine,” and three seconds later, said, “We’re losing an engine.” The captain asked “Why?” The first officer responded, “Fuel.” The captain again asked “Why?”
At 18:07:06, Flight Engineer Mendenhall reported that the engine had “flamed out” (stopped running due to fuel exhaustion). Captain McBroom called Portland Approach Control and requested an immediate clearance to land at PDX, “now.” The airliner was then 18 miles south of the airport. McBroom asked Mendenhall to reset the landing gear circuit breakers. “See if we get gear lights.”
At 18:13:21, Mendenhall said, “We just lost two engines, guys.” Four seconds later, he said, “We just lost two engines—one and two.” [Both engines on the left wing.] McBroom said, “They’re all going,” and told First Officer Beebe to declare an emergency.
At 18:13:50, Beebe called, “Portland Tower, United One-Seventy-Three Heavy, mayday. We’re—The engines are flaming out. We’re going down. We’re not able to make the airport.” There were no further transmissions.
At approximately 18:15, United Flight 173 crashed in a residential area, about 6 nautical miles (11 kilometers) southeast of Portland International Airport. Eight passengers were killed, along with Flight Engineer Mendenhall and Senior Flight Attendant Joan Newton Wheeler. Another 23 persons were seriously injured. Two unoccupied homes were destroyed.

The National Transportation Safety Board (NTSB) investigation found:
3.2 Probable Cause
The National Transportation Safety Board determined that the probable cause of the accident was the failure of the captain to monitor properly the aircraft’s fuel state and to properly respond to the low fuel state and the crew-members’ advisories regarding fuel state. This resulted in fuel exhaustion to all engines. His inattention resulted from preoccupation with a landing gear malfunction and preparations for a landing emergency.
Contributing to the accident was the failure of the other two flight crewmembers either to fully comprehend the criticality of the fuel state or to successfully communicate their concern to the captain.
—NATIONAL TRANSPORTATION SAFETY BOARD AIRCRAFT ACCIDENT REPORT NTSB-AAR-79-7 , 7 June 1979, at Page 29
United Airlines Flight 173 crashed in a wooded area, southeast of PDX.
When the landing gear was lowered, a gear retraction cylinder failed, allowing the right main gear to fall into place. It locked, but a microswitch which should have activated the landing gear indicator light was damaged.
United Airlines’ operations manual required that the crew have the control tower make a visual check that the gear was down. Though it could not confirm that the gear was locked, if the visual check indicaated that landing gear appeared to be down, a landing was authorized. Captain McBroom deviated from this procedure.
The airliner was a McDonnell Douglas DC-8-61, serial number 45972, which had been delivered to United Airlines on 22 May 1968. At the time of the accident, it had flown a total of 33,114:33 hours.

The DC-8-61 is a four-engine turbojet-powered airliner with swept wings. It was a “stretched” variant of the basic DC-8 design, capable of carrying a maximum of 259 passengers. A 240 inch (6.096 meters) “plug” was installed forward of the wings and a 200 inch (5.08 meters) plug aft. This gave the airliner a total length of 187.4 feet (57.12 meters), with a wingspan of 142.4 feet (43.40 meters) and maximum height of 43 feet, 5.2 inches (13.239 meters). N8082 had a zero fuel weight of 201,927 pounds (91,592.6 kilograms), and a maximum certified takeoff weight (MTOW) of 325,000 pounds (147,418 kilograms). The maximum usable fuel was 23,393 U.S. gallons (88,552 liters).
The DC-8-61 was powered by four Pratt & Whitney Turbo Wasp JT3D-3B engines. This engine was a civil variant of the military TF33 series. The JT3D-7 was a two-spool axial-flow turbojet engine with a 2-stage fan, 14-stage compressor (7 intermediate-, 7 high-pressure stages) and 4-stage turbine (1 high- and 3 low-pressure stages). The JT3D-3B had a maximum power rating of 18,000 pounds of thrust. The engine was 145.5 inches (3.696 meters) long, 53 inches (1.346 meters) in diameter, and weighed 4,340 pounds (1,969 kilograms).
The DC-8-61 had a cruise speed of 0.82 Mach, and a maximum range of 3,200 nautical miles (5,926 kilometers). During a test flight at Edwards Air Force Base, 21 August 1961, a Douglas DC-8-43, N9604Z, reached Mach 1.1012.

2 December 1955: The prototype de Havilland DH-106 Comet 3, G-ANLO, departed Hatfield Aerodrome, Hertfordshire, England, with Chief Test Pilot John Cunningham and Per Buggé in the cockpit. R.W. Chandler was the navigator/radio operator. Other crew members included Chief Flight Engineer E. Brackstone Brown, and flight engineers R.V. Ablett and J. Hamilton.
Several de Havilland executives and engineers were among the passengers. Captain A.P.W. Cane of British Overseas Airways Corporation and Captain I.D.V. Ralfe of Qantas were aboard to observe to new airliner in operation.
De Havilland DH.106 Comet 3 G-ANLO was delayed by heavy fog at Hatfield, 2 December 1955. (De Havilland)
Departure had been scheduled for 5:30 a.m., local time, but heavy fog delayed the flight. 5 hours, 3 minutes later, the Comet 3 landed at Cairo, Egypt, after flying 2,076 nautical miles (2,389 statute miles, 3,845 kilometers). Rather than continuing on as had originally been planned, the crew remained over night at Cairo.
G-ANLO left Cairo the following morning and with refueling stops at Bombay, Maharashtra India; Singapore, Colony of Singapore; and Darwin, Northern Territory, Australia; the airliner arrived at Sydney, New South Wales, Australia, on 4 December, after a total of 19 hours, 5 minutes of flight. The distance traveled was 8,728 nautical miles (10,044 statute miles, 16,164 kilometers). During the Singapore-Darwin leg, the Comet 3 cruised at 44,000 feet (13,411 meters). More than 20,000 people were waiting at Sydney Kingsford Smith Airport to see the new jetliner arrive.

Group Captain Cunningham made demonstration flights from Sydney to Melbourne, Canberra and Perth.
G-ANLO then continued to Auckland, New Zealand, flying the 1,166 nautical miles (1,342 miles, 2,159 kilometers) in 2 hours, 43 minutes. From Auckland to Nadi Airport, Fiji, 1,153 nautical miles (1,326 miles, 2,135 kilometers), took 2 hours, 52 minutes.
The next leg of the around the world tour, Fiji to Honolulu, in the Hawaiian Islands, was completed on 13 December. The Comet 3 covered the 2,791 nautical miles (3,212 statute miles, 5,169 kilometers) in 6 hours, 44 minutes. G-ANLO remained at Honolulu for the next two days.

On 15 December, the Comet 3 left Honolulu for Vancouver, British Columbia, Canada, 2,408 nautical miles (2,771 statute miles, 4,460 kilometers). The duration of this flight was 5 hours, 40 minutes. The Comet 3 flew across Canada to Toronto, Ontario, 1,898 nautical miles (2,184 statute miles, 3,515 kilometers) in 3 hours, 56 minutes, then on to Montreal, Quebec, arriving there on 20 December.
The final leg of the flight, Montreal to London Heathrow Airport, 2,907 nautical miles (3,345 statute miles, 5,384 kilometers) was completed in 6 hours, 9 minutes, on 27 December 1955.
This was the first around-the-world flight by a jet-powered aircraft. The total distance flown by the Comet 3 was 24,324 nautical miles (27,991.6 statute miles/45,048.1 kilometers) The total flight time was 56 hours, 17 minutes.
For this flight Group Captain Cunningham was awarded the Harmon Trophy, which was presented by President Dwight D. Eisenhower, 23 October 1956.
The de Havilland DH.106 Comet 3 was a further development of the Comet 2 series. It was 15 feet (4.572 meters) longer with a length of 111 feet, 6 inches (33.985 meters), a wingspan of 115 feet (35.052 meters) and overall height of 29 feet, 6 inches (8.992. The area of the wings and tail surfaces had been increased. It was powered by four Rolls Royce Avon 521 turbojet engines, rated at 10,000 pounds of thrust (44.48 kilonewtons), each.

The airliner was designed to carry 58–76 passengers on flights ranging to 2,600 miles (4,184 kilometers). In addition to the increased length, visual differences from the previous Comets were the circular passenger windows, and wing tanks extending forward from the wings’ leading edges.
Only two Comet 3s were built and one was used as a static test article. Production continued with the Comet 4, which had even greater improvements. G-ANLO remained a development prototype and was modified several times. In 1958 the wings were shortened and the external wing tanks removed. The airplane was redesignated Comet 3B. It was turned over to the Ministry of Supply and re-registered XP915, 20 June 1961. The airplane was used in instrument landing tests and later converted to a mockup of the Hawker Siddeley Nimrod MR1 maritime patrol aircraft. It was taken out of service in 1966 and scrapped.

Group Captain John Cunningham C.B.E., D.S.O. and Two Bars, D.F.C. and Bar, A.E., was born 1917 and educated at Croydon. In 1935 he became an apprentice at De Havilland’s and also joined the Auxiliary Air Force, where he trained as a pilot. Cunningham was called to active duty in August 1939, just before World War II began.
Promoted to Group Captain in 1944, Cunningham was the highest scoring Royal Air Force night fighter pilot of World War II, credited with shooting down 20 enemy airplanes. He was responsible for the myth that eating carrots would improve night vision.
Following the War, John Cunningham returned to de Havilland as a test pilot. Following the death of Geoffrey Raoul de Havilland, Jr., in 1946, Cunningham became the de Havilland’s chief test pilot. He remained with the firm through a series of mergers, finally retiring in 1980.
He set a Fédération Aéronautique Internationale (FAI) world speed and altitude record with the company’s DH.100 Vampire jet fighter, TG278: 799.644 kilometers per hour (496.876 miles per hour) over a 100 kilometer course at Lympne Airport, 31 August 1947.¹ He flew the DH.100 to 18,119 meters (59,446 feet) over Hatfield Aerodrome, 23 March 1948.² On 24 April 1950, Cunningham flew a DH.106 Comet Mk.I from London to Cairo at an average speed of 686.56 kilometers per hour (426.61 miles per hour), setting a world record for speed over a recognized course.³
Group Captain Cunningham died 21 July 2002 at the age of 84 years.
Per Olivarius Buggé (also known as Peter Bugge) was born at Kristiansund, Norway in 1918. He joined the Royal Norwegian Air Force in 1938. After Germany invaded the country, Buggé escaped to Sweden, April 1940, and in February 1941 arrived in Great Britain. He served with the Royal Air Force for the remainder of the War, flying Bristol Beaufighters and de Havilland Mosquitos with No. 604 Squadron and No. 85 Squadron (while it was under the command of Squadron Leader John Cunningham).
After the War Buggé flew for British Overseas Airways Corporation and Swedish Airlines. In 1949, he joined de Havilland as a test pilot, and stayed with the company after it was absorbed by Hawker Siddeley. He died in 1998.
