Gossamer AlbatrossOn this date in history, June 12, 1979, the first successful crossing of the English Channel in a human-powered aircraft took place.  Bryan Allen flew the Gossamer Albatross across the English Channel powered only by the pilot pedaling a bicycle-like contraption that drove a large two-bladed propeller.

QUESTION:

How long did it take to fly across the English Channel in the first human-powered aircraft?

ANSWER:

2 hours 49 minutes

EXPLANATION:

The Gossamer Albatross was designed and built by a team led by Paul B. MacCready, a noted aeronautics engineer, designer, and soaring champion. The Gossamer Albatross was his second human-powered aircraft. The Gossamer Condor, won the first Kremer prize on August 23, 1977 by completing a mile-long figure-eight course. The second Kremer challenge was then announced as a flight across the English Channel.

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. The empty weight of the airplane was only 71 pounds. To maintain the craft in the air it was designed with very long tapering, like those of a glider, allowing the flight to be undertaken with a minimum of power.

On June 12, 1979, piloted by amateur cyclist Bryan Allen, it completed the 22.2 mile crossing in 2 hours and 49 minutes, achieving a top speed of 18 mph and an average altitude of 5 feet.
