The Potez 34 was a recording breaking aircraft, designed and built in France in the late 1920s. Only one was completed.
Design and development
[edit]The Potez 34 was built by Aéroplanes Henry Potez and was derived from the Potez 28M and used the Ryan NYP's blind flying / periscope configuration.[1]
Intended to win the distance record in closed circuit and then in a straight line, the first record attempts of the Potez 34 were punctuated by tyre punctures and oil leaks. Modifications were made including the exchange of the Farman engine with a lighter Hispano-Suiza and the adoption of a metal propeller. On 18 June 1929, the French distance in closed circuit record was beaten over a course of 6,517 km (4,049 mi) flown by Lionel de Marmier and Louis Favreau, but the world record could not be broken due to a technical failure.[2] On 25 June 1929, the same crew attempted to break the distance record in a straight line, flying to the Far East, but propeller vibrations necessitated a landing in Tunisia and the failure of the attempt.
The Potez 34 was lent by the Ministere de l'Air to Joseph Le Brix, assisted by Maurice Rossi, for a flight from Paris to Saigon, with three stops at Benghazi, Basra and Allahabad. The attempt began 16 December 1929 and a breakdown occurred over Burma on the night of 22 to 23 December 1929, the aircraft crashed into the jungle but the crew parachuted to safety.[3]
