Bristol Blenheim

Bristol’s Blenheim originated as a light transport design by Frank Barnwell, and was brought to reality by a requirement by the Daily Mail for what, in later years, would be termed an executive aircraft. The resulting Mercury-powered Bristol Type 142 of 1935 lived up to the newspaper’s speed requirements, being significantly faster than front line RAF fighters of the day. The Type 143 was similar, save for the Bristol Aquila engines used on the second aircraft.

Air Ministry interest in the Type 142 had been high from the start, and within a few months of the first flight an order was placed for 150 Type 142M bomber derivatives under Specification B.28/35, these receiving the name Blenheim.

The last production version of the type, the Type 160 entered service as the Blenheim MkV with No.18 Squadron. This mark entered service with a glass nose, but had actually originated as the solid-nosed Bisley prototype.
