Kremer prize

The Kremer prizes are a series of monetary awards, established in 1959 by the industrialist Henry Kremer, that are given to pioneers of human-powered flight. The competitions and prize awards are administered by the Royal Aeronautical Society's Human Powered Flight Group.
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 above the ground.
The second Kremer prize of £100,000 was won on 12 June 1979, again by Paul MacCready, when Bryan Allen flew MacCready's Gossamer Albatross from England to France.
A Kremer prize of £20,000 for speed was won in 1984 by a design team of the Massachusetts Institute of Technology for flying their MIT Monarch B craft on a triangular course in under three minutes (for an average speed of ). Further segments of a total prize pot of £100,000 were to be awarded for every improvement in speed of at least 5%; the next segment was won in the MacCready Bionic Bat with a flight of 163.28 seconds on 18 July 1984, piloted by Parker MacCready. The third segment was won by Holger Rochelt flying Musculair 1 designed by Günther Rochelt. The fourth segment was won on 2 December 1984, with a flight of 143.08 seconds in the MacCready Bionic Bat piloted by Bryan Allen. The fifth and final segment was won with a flight of 122.01 seconds by Holger Rochelt flying Musculair 2, after which the prize competition was withdrawn by the Royal Aeronautical Society on grounds of safety.
There are currently three Kremer Prizes that have not yet been awarded, for a total of £150,000:
