The Gossamer Albatross is a human-powered aircraft built by American aeronautical engineer Dr Paul B MacCready's company AeroVironment.
The Gossamer Albatross was constructed using a carbon fiber frame, with the ribs of the wings made with expanded polystyrene; the entire structure was then wrapped in a thin, transparent plastic (mylar PET film).
To maintain the craft in the air, it was designed with very long, tapering wings (high aspect ratio), like those of a glider, allowing the flight to be undertaken with a minimum of power.
[2] Just before 6 am on June 12, 1979, amateur cyclist and pilot Bryan Allen powered the Albatross to the rehearsed speed of 75 revolutions per minute and took off from a point near Folkestone, England.
Allen completed the 22.2-mile (35.7 km) crossing in 2 hours and 49 minutes, achieving a top speed of 18 mph (29 km/h) and an average altitude of 5 ft (1.5 m).
