Narrative:
The Boulton & Paul P.64 Mailplane also known as the Mail-Carrier was a 1930s British twin-engined all-metal biplane transport aircraft designed for Imperial Airways and built by Boulton & Paul Ltd.

The airline had a requirement, which was translated into Air Ministry specification 21/28, for a mailplane to carry a 1,000 lb (454 kg) payload on a 1,000 mile (1,609 km) leg at a reasonable speed. Boulton & Paul designed and constructed the prototype P.64 Mailplane to address these requirements. The aircraft (registered G-ABYK on 14 July 1932) first flew in March 1933 at the company's Norwich HQ at Mousehold Aerodrome, Norwich, Norfolk. It was not a success, deemed to be expensive and unsatisfactory. It was destroyed during trials at Martlesham Heath when it struck the ground during an unexplained dive on 21 October 1933. Pilot - Flt Lt Gordon Lennox George Richmond - was injured

The company then addressed the specification's requirements with a new design transport aircraft which was lighter, slimmer and longer (the Boulton Paul P.71A).

Registration G-ABYK cancelled in January 1934 due to "destruction or permanent withdrawal from use of aircraft"
