Project Manhigh was established in December 1955 to obtain scientific data on the behavior of a balloon in an environment above 99% of the earth's atmosphere and to investigate cosmic rays and their effects on man. Three balloon flights to the edge of space were made during the program: Manhigh 1 to 29.6 km, by Captain Joseph Kittinger on 2 June 1957; Manhigh II to 30.95 km, by Major David Simons on 19 and 20 August, 1957; and Manhigh III to 29.9 km by Lieutenant Clifton McClure on 8 October 1958. Including the pilot and scientific equipment carried aboard, the total weight of the Manhigh II gondola was 747 kg. At maximum altitude, the ballon expanded to a diameter of 60 m with a volume in excess of 85,000 cubic m.
