Handley Page HP.75 Manx
From 1936 Dr. Gustav Victor Lachmann concentrated on researchwith tailless aircraft, starting with the development of the H.P.75 Manx. This was completed in 1939, but Lachmann was interned for the duration of the war, and its development was completed by Godfrey Lee.
The airframe was built by Dart Aircraft of Dunstable, England; the aircraft was finished at Radlett, England. During taxi trials on 12 September 1942, the aircraft flew unintentionally at a height of 12 ft (3.66 m) and was subsequently damaged while landing.
Marked with the ‘Class B’ markings* H-0222, the aircraft flew for the first time on 25 June 1943. Handley Page chief test pilot Fit Lt James Talbot flew the small H.P.75 for the first time at the company's airfield at Radlett in Hertfordshire. Talbot reported that the H.P.75 flew well but had high drag owing to its fixed undercarriage. In 1945 it was designated H.P.75 for the first time.
After modification it flew again, but interest waned and it last flew on April 3, 1946. A total of 31 flights were made till 3 April 1946 (total flight time 17 hr 43 min) when the aircraft was stored and subsequently scrapped in 1952.
