The story
In 1934 Lord Rothermere, owner of the Daily Mail, ordered a fast private aircraft from Bristol. The Type 142, named Britain First, flew in 1935 at 307 mph, faster than the fighters then in RAF service, and it became the Blenheim bomber. By 1940 faster fighters had erased that lead and losses were heavy, but the Blenheim was there from the first day: on 3 September 1939 Blenheim N6215 became the first British aircraft to cross the German coast. Blenheims were also the first British fighters fitted with radar. Over 4,400 were built, including licence production in Canada and Finland. One flies today.
The world's only flying Blenheim, G-BPIV, has been rebuilt twice. A Canadian-built Bolingbroke, it first flew restored in 1993, was damaged landing at Duxford in 2003, and flew again in 2014 with a short Mk I nose.
