Vickers Wellington LN514 was a Vickers Wellington bomber built in 1943 in record time, as part of a British propaganda effort during the Second World War. The bomber was constructed in 23 hours and 50 minutes, and took off 24 hours and 48 minutes after the first parts of the airframe had been laid down, beating the previous record of 48 hours set by an American factory. It was constructed at the Vickers-Armstrongs factory in Broughton, Flintshire. The record attempt was the idea of the government to bolster morale at home and send a message abroad that British wartime manufacturing capacity was unaffected by German bombing.
