The Handley Page Hastings was a large purpose-built four-engined transport aircraft. It was furnished with several modern features, such as a Messier-built fully retractable undercarriage, which was operated hydraulically, and unprecedented stowage space for an RAF transport aircraft. Roughly 3,000 cubic feet of unrestricted area was used to house various cargoes or passengers. The cabin was fitted with a Plymax floor, complete with various grooves, channels, and lashing points for securing goods of varying sizes, while the walls were sound proofed and lined with plywood for increased comfort. Principal access is provided by a freight door on the port side, which incorporates a paratroop door, while a second paratroop door is present on the starboard side; on the ground, an rapidly deployable ramp suitable for road vehicles can also be used. In service, the aircraft was typically operated by a crew of five; it could accommodate either up to 30 paratroopers, 32 stretchers and 28 sitting casualties, or a maximum of 50 fully equipped troops.
