De Havilland DH.14 Okapi

The de Havilland DH.14 Okapi was a British two-seat day bomber designed as a replacement for the Airco DH.4 and DH.9 but never put into production. It was essentially a scaled-up DH.9 with a bigger engine, the Rolls-Royce Condor. Three were built, but with the First World War over the Royal Air Force was reluctant to accept them. The third aircraft was the first to fly and was completed by Airco as the DH.14A, a two-seat long-range mail plane; it was loaned to Cotton in an attempt on the first flight between London and Cape Town that began from Hendon on 4 February 1920 but ended in a forced landing at Cricklewood. The other two military aircraft were completed by de Havilland at Stag Lane in 1921 and used for trials. One suffered a fatal crash at Burnham Beeches on 10 February 1922, and no production aircraft were ordered.
