Originally designed as a Torpedo Bomber for the Royal Navy for which no orders developed, the PV-3, which was based on the Wapiti, was acquired by the Royal Geographical Society and modified for an expedition to fly over the summit of Everest (8,848m/29,030ft). The flight was financed by Lady Houston and successfully completed on 3rd April 1933, to much acclaim in the press. The PV-3 was accompanied by the Westland PV-6 which was subsequently developed to become the Wallace.
