The Southampton University Man Powered Aircraft (or SUMPAC) was a human-powered aircraft built by British university students between 1960 and 1961. The aircraft was designed for an attempt at the Kremer prize, failing to complete the course to claim the prize money the SUMPAC did fly successfully on several occasions.[1]

The aircraft was designed and built by a team of post-graduate students from Southampton University. Intended to compete for the £50,000 Kremer Prize (requiring successful completion of a one mile (1.6 km) 'figure of eight' course) the project was funded by the Royal Aeronautical Society.[1]
The aircraft is of conventional configuration, with the exception of a pylon mounted pusher propeller, and is constructed from balsa, plywood and aluminium alloy. Originally covered with silver-doped Nylon the aircraft now sports a transparent plastic skin on the fuselage.
The SUMPAC was powered using pedals and chains to drive a large two-bladed propeller. Piloted by noted gliding instructor and test pilot Derek Piggott, its first flight on 9 November 1961 at Lasham airfield covered a distance of 70 yards (64 m) and climbed to a height of six feet (1.8 m).[1] The longest flight made was 650 yards (594 m) rising to a maximum height of 15 ft (4.6 m). After a crash in 1963 which caused damage to the fragile structure it was decided to retire the aircraft although it had been repaired.[1]
The SUMPAC is currently on display at the Solent Sky museum, it was loaned for some time to the Shuttleworth Collection but now resides in its hometown of Southampton.
