The speed to fly is the optimum speed through sinking or rising air mass to achieve either the furthest glide, or fastest average cross-country speed. [1] Most speed to fly setups use units of either airspeed in kilometers per hour (km/h) and climb rate in meters per second (m/s), or airspeed in knots (kn) and climb rate in feet per minute (ft ...
The first Kremer prize of £50,000 was won on 23 August 1977 by Dr. Paul MacCready when his Gossamer Condor, piloted by Bryan Allen, was the first human-powered aircraft to fly a figure eight around two markers one half mile apart, starting and ending the course at least 10 feet (3.0 m) above the ground.

Although slow, cruising at only 11 mph (18 km/h), it achieved that speed with only 0.35 hp (0.26 kW). [20] The second Kremer prize of £100,000 was won on June 12, 1979, again by Paul MacCready, when Bryan Allen flew MacCready's Gossamer Albatross from England to France: a straight distance of 35.82 km (22 miles 453 yards) in 2 hours, 49 minutes.
The aircraft was designed and built by a team led by Paul B. MacCready, a noted American aeronautics engineer, designer, and world soaring champion. Gossamer Albatross was his second human-powered aircraft, the first being the Gossamer Condor, which had won the first Kremer prize on August 23, 1977, by completing a 1-mile (1.6 km)-long figure-eight course.
