Airspeed AS.5 Courier
A light transport of conventional all-wood construction, with all con¬trol surfaces fabric-covered, of 1935. The first British aircraft with retractable undercarriage to go into production, a five-six-seat cantilever low-wing cabin monoplane.
First flown on 11 April 1933 (G-ABXN) from Portsmouth, four days later it crashed at Portsmouth, receiving minor damage. Repaired, it had another accident at RAF Martlesham Heath. It was used in aerial refuelling experiments by Sir Alan Cobham, using two Handley Page W10s as aerial tankers. The experiments led to an attempt of a non-stop flight to India that started at Portsmouth on 24 September 1934. It ended the same day when Cobham had to make a forced landing at Malta, due to a broken throttle; in the event the Courier was damaged. The aircraft was impressed into the RAF in June 1940, s/n X9427.
Sixteen were built with a total of 15 production aircraft.
