Westland's big apple, the Westminster was based on the Sikorsky S-56's dynamic systems with Napier Eland turbine engines. G-APLE had an open steel tube frame, which was nicely clad in fabric over wooden formers a few months before the project was cancelled in 1960. Photo from: Nationaal Archief (Netherlands)
