Sopwith Aviation Company
In 1919, the Sopwith Aviation Company developed a three-seat transport aircraft, the Sopwith Antelope, based on its Wallaby long-range aircraft built to compete for a £10,000 prize for an England-Australia flight, which was in turn based on the Sopwith Atlantic, which had crashed during an attempt to be the first aircraft cross the Atlantic Ocean non-stop earlier that year.
