Miss Amy Johnson, who flew alone to Australia several months ago, arrived at the Stag Lane aerodrome this morning in readiness for a flight to Peking by way of Berlin, Warsaw, Moscow, and Omsk. From Omsk she will follow the Trans-Siberian railway.
Owing to fog she was unable to start on her journey immediately. But she left at 20 minutes to 11 o’clock.
Miss Johnson wore a green leather flying suit and parachute, strapped to her back. As she entered the cockpit of the Gipsy Moth aeroplane, with which she was presented after her trip to Australia, she carried a parcel of biscuits, chocolate, and tea. Only two dozen persons saw her start. She does not intend to hurry.
5 July 1927: Less than one year after learning to fly an airplane, Lady Bailey, with Mrs. Geoffrey de Havilland (the former Miss Louise Thomas) as a passenger, took off from the de Havilland airfield at Stag Lane, Edgeware, London, England, and climbed to an altitude of 5,268 meters (17,283 feet) setting a Fédération Aéronautique Internationale (FAI) World Record for multi-place light aircraft.¹ (Mrs. de Havilland is listed as “crew” in the FAI record.)
Lady Bailey was flying Captain Geoffrey de Havilland’s personal airplane, a DH.60X Moth, construction number 276, registration G-EBQH.
Lady Bailey was born Mary Westenra, daughter of the 5th Baron Rossmore. She married Sir Abe Bailey at the age of 20. Soon after becoming a licensed pilot in early 1927 (Royal Aero Club Aviator’s Certificate 8067), she flew across the Irish Sea, the first woman to do so. After her World Record altitude flight, she set several long distance solo flight records, including an 8,000-mile (12,875 kilometers)flight from Croydon, South London to Cape Town, South Africa with a DH.60 Cirrus II Moth, G-EBSF, and an 10,000-mile (16,093 kilometers) return flight made with another DH.60 (after G-EBSF was damaged). These were the longest solo flight and the longest flight by a woman to that time.
Lady Bailey was twice awarded the Harmon Trophy (1927, 1928). In 1930, she was invested Dame Commander of the Order of the British Empire. During World War II, The Hon. Dame Mary Bailey, D.B.E., served with the Women’s Auxiliary Air Force with the rank of Section Officer, equivalent to a Royal Air Force sergeant.
Lady Mary died 29 July 1960 at the age of 70.
The de Havilland DH.60 was a light-weight, two-place, single-engine, single-bay biplane. The fuselage was covered with plywood and the wings and tail surfaces were covered with fabric. It was 23 feet, 5½ inches (7.150 meters) long with a wingspan of 29 feet, 0 inches (8.839 meters) and overall height of 8 feet, 9½ inches (2.680 meters). The airplane was designed so that the wings could be folded parallel to the fuselage, giving it an approximate width of 9 feet (2.7 meters). The wings had a chord of 4 feet, 3 inches (1.295 meters). The vertical gap between the wings was 4 feet, 10 inches (1.473 meters) and lower wing was staggered 3 inches (7.62 centimeters) behind the upper. Both wings had 3.5° angle of incidence and 3.5° dihedral. There was no sweep. Empty, the DH.60 had a weight of 764 pounds (346.6 kilograms) and loaded weight of 1,650 pounds (748 kilograms).
G-EBQH was a prototype for the de Havilland DH.60 Cirrus II Moth, and was powered by an air-cooled, normally-aspirated 304.66-cubic-inch-displacement (4.993 liter) A.D.C. Cirrus Mark II four-cylinder vertical inline engine. This was a right-hand tractor, direct-drive, overhead-valve engine with two valves per cylinder and a compression ratio of 4.9:1. It had a normal power rating of 75 horsepower at 1,800 r.p.m. and a maximum power rating of 80 horsepower at 2,000 r.p.m. It drove a two-bladed, fixed-pitch propeller. The Cirrus Mk.II was 3 feet, 9.3 inches (1.151 meters) long, 1 foot, 7 inches wide (0.483 meters) and 2 feet, 11.6 inches (0.904 meters) high. It weighed 280 pounds (127 kilograms).
G-EBQH was used as a factory demonstrator and test aircraft. The DH.60X crashed in February 1928 but was rebuilt and later sold. It was flown in the King’s Cup Air Races of 1927, 1928 and 1929 by Alan S. Butler, the chairman of de Havilland. The prototype was modified to a single-place configuration with a Cirrus Mark III engine, and was known as the Moth Special. In the 1929 race, it set the fastest time for a light aircraft.
Records indicate that G-EBQH changed ownership a number of times. Its Certificate of Airworthiness expired in 1937 and its status is not known.
22 February 1925: At the de Havilland Aircraft Company airfield at Stag Lane, Edgware, London, Geoffrey de Havilland, O.B.E., took his new DH.60 Moth, c/n 168 (later registered G-EBKT), for its first flight.
The DH.60 was a light-weight, two-place, single-engine, single-bay biplane. The fuselage was constructed of plywood and the wings and tail surfaces were covered with fabric. The Moth was 23 feet, 5½ inches (7.150 meters) long with a wingspan of 29 feet, 0 inches (8.839 meters) and overall height of 8 feet, 9½ inches (2.680 meters). The airplane was designed so that the wings could be folded parallel to the fuselage, giving it an approximate width of 9 feet (2.7 meters).
The wings had a chord of 4 feet, 3 inches and the lower wing was staggered slightly behind the upper. Their total area was 229.0 square feet (21.3 square meters). The vertical gap between the wings was 4 feet, 10 inches (1.473 meters) and lower wing was staggered 3 inches (7.62 centimeters) behind the upper. Both wings had 3.5° angle of incidence and 3.5° dihedral. There was no sweep.
The DH.60 had an empty weight of 764 pounds (346.6 kilograms) and its gross weight was 1,650 pounds (748 kilograms).
The Moth was powered by an air-cooled, normally-aspirated 4.503 liter (274.771-cubic-inch-displacement A.D.C. Aircraft Ltd., Cirrus inline 4-cylinder overhead valve engine with two valves per cylinder and a compression ratio of 5.4:1. The direct-drive engine produced 60 horsepower at 1,800 r.p.m., and 65 horsepower at 2,000 r.p.m. The Cirrus was 0.983 meters (3.225 feet) long, 0.908 meters (2.979 feet) high and 0.450 meters (1.476 feet) wide. It weighed 260 pounds (118 kilograms). The A.D.C. Cirrus was designed by Major Frank Bernard Halford, who later designed the de Havilland Gipsy engine, as well as the Goblin and Ghost turbojet engines.
De Havilland built 8 pre-production and 31 production DH.60 Moths. 595 DH.60s of all variants were produced at Stag Lane.
On 29 May 1925, Alan Cobham flew the prototype from Croydon to Zurich and back in 14 hours, 49 minutes. Cobham also flew the Moth in The Kings Cup Air Race, though weather forced him to land short of the finish. It placed second in a follow-up race.
The G-EBKT was used as a demonstrator for de Havilland for a brief time before being sold to Sophie C. Elliot Lynn, 26 March 1926. She flew the Moth in the Paris Concours d’Avions Economiques in August 1926. (Mrs. Elliott Lynn later became Mary, Lady Heath.)
In 1927, G-EBKT was sold to the London Aeroplane Club. It crashed at Dennis Lane, Stanmore, Middlesex, 21 August 1927, injuring the pilot and a passenger:
On Sunday afternoon, Pilot Officer Stanley Pritchard-Barrett, flying on D.H. “Moth” G-EBKT with his wife as passenger, crashed in the grounds of the residence of Major Sir Maurice FitzGerald,Bt. He was severely injured about his head, and his wife, who was a passenger, had a leg broken. The machine fell from a height of about 90 ft.
The London Aeroplane Club “Moth” is apparently a complete write-off.
G-EBKT’s registration was cancelled 20 January 1928.
