Development
The airline had a requirement, which was translated into Air Ministry specification 21/28, for a mailplane to carry a Script error: No such module "convert". payload on a Script error: No such module "convert". leg at a speed of at least Script error: No such module "convert"..[1] Boulton & Paul designed and constructed the prototype P.64 Mailplane to address these requirements.[1] The P.64 was a twin-engine two-bay equi-span biplane. It was powered by two Bristol Pegasus IM2 supercharged radial engines rated at Script error: No such module "convert". driving two-bladed fixed pitch propellers and mounted under the upper wings.[2]
The aircraft (registered G-ABYK) first flew in March 1933 at the company Norwich. 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.
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).
