19–20 August 1957: At 9:22 a.m., CDT (1422 UTC), 19 August 1957, Major David G. Simons, M.D., United States Air Force, lifted off aboard a helium-filled balloon at an open pit mine near Crosby, New Hampshire. This was the second flight of Project MANHIGH, MANHIGH II. This was a series of experiments to investigate the physiological effects of extreme high altitude flight. The balloon and its 1,648 pound (748 kilogram) gondola were deployed from the bottom of Portland Mine as protection from wind while it inflated.

After 2 hours, 18 minutes, Major Simon had reached 100,000 feet above the surface of the Earth. The peak altitude was a record-setting 101,516 feet (30,942 meters). While at altitude, Dr. Simon performed 25 aeromedical experiments.

32 hours, 10 minutes after lift off, at 5:32 p.m., CDT (2232 UTC), 20 August, the MANHIGH II gondola touched down 10 miles northwest of Frederick, South Dakota. Major Simons was awarded the Distinguished Flying Cross.

Prof. Dr. Dr. h.c. David G. Simons, M.D., Ph.D., Hon., was a world leading authority on chronic and myofascial pain. He died in 2010.
