Boulton & Paul P64 Mailplane

boultonp64mailplane

 

In 1933 Boulton & Paul built a twin-engine all-metal biplane under a contract awarded by Imperial Airways for a mailplane capable of carrying a 454kg payload over a 1609km range at reasonable speed. First flown at the company's airfield at Mousehold, Norwich, in March 1933, it lasted barely seven months before being destroyed in an unexplained fatal crash during trials at Martlesham Heath in October.


It was considered expensive and unsatisfactory, and developed into the P71A Mailplane.
