History
The original Blenheim bomber evolved from a Bristol light transport development, probably the first aircraft specifically designed as a high-speed executive transport. Labeled the Model 142 “Britain First”, the airplane was displayed at the 1935 Hendon display. RAF leaders immediately saw its potential as a light bomber, and after protracted development, it emerged as the Model 142M, a mid-wing, three place twin-engine bomber with a crew of 3. Only two machine guns were installed, and a total of 986 Mk. I’s was produced before it was replaced by the Mk. IV model, of which 2703 were built.
