Bristol B.142 Britain First


In the early-1930s, a design for a fast twin-engined monoplane transport, in which use was made of stressed skin construction, attracted the interest of the then Lord Rothermere. He agreed to sponsor the construction of a development of the design, known as the Type 142 'Britain First' as his personal high speed transport and first flying on 12 April 1935. Powered by two 485kW Bristol Mercury VIS engines, during official trials in 1935 this monoplane achieved a top speed of 307 mph - 50mph faster than any fighter then in service. When the Air Ministry asked to retain the aircraft for evaluation as a bomber, Lord Rothermere presented it to the Air Council and thereafter the development of the Type 142 into the military Blenheim proceeded rapidly. Within three months of the Type 142M acceptance trials in June 1935, Filton had received an order for 150 Blenheims.
