in october 1904, ernest archdeacon joined deutsch de la meurthe to offer a prize of 50,000 francs for the first heavier-than-air flight around a one kilometre closed circuit. the sum represented about 20 times the annual earnings of a parisian professional worker. archdeacon and de la meurthe understood that apart from the wrights (see below), all heavier-than-air flights had been in a straight line. the prize was intended to encourage the development of an airplane that could turn, so the prize winner would have to fly a closed circuit.
