Boulton & Paul P71A Mailplane
Development from the P.64, the Boulton & Paul P.71A was lighter, slimmer and longer. The P.71A had 365kW Armstrong Siddeley Jaguar VIAs, in place of the 414kW Bristol Pegasus engines of the P.64 and two aircraft were delivered to Imperial Airways at Croydon in February 1935.
The airline had lost interest in mail-carrying possibilities and the two aircraft, named Boadicea and Britomart, were converted for passenger carrying with 13 seats, which were easily removable if the aircraft were required for use as light freighters.
The P.71As were both lost within 19 months of delivery. The first of them was damaged beyond repair in a landing accident at Brussels in October 1935. The second disappeared over the English Channel in September 1936.
