During the third week of May 1959, a series of low altitude manned balloon flights were flown to train Fulgham and Kaufman.[170] These flights were launched by the Holloman AFB Balloon Branch. To satisfy safety requirements, the flights were closely monitored by medical personnel at all times. A helicopter with medical personnel followed the flights during daylight hours, a C-131 aircraft followed during hours of darkness, and at all times medical personnel followed in an ambulance.[171] Balloon recovery and communications technicians also followed the missions on the ground in a communications vehicle and a balloon recovery vehicle.[172] The safety requirements were a result of several recent balloon mishaps that resulted in serious injuries to the pilots.
To meet the training schedule, Kittinger, Kaufman and Fulgham were assigned temporary duty (TDY) from the Aero Medical Laboratory at Wright-Patterson AFB to the Balloon Branch at Holloman AFB, N.M.

Winzen (_right_) and space physiologist Capt. Grover Schock (_left_), were seriously injured in a balloon accident near Ashland, Wisc. Additionally, two training flights at Holloman AFB also resulted in injuries to pilots. These injuries prompted Air Force officials to require close medical supervision during future training flights. (_photo courtesy of Mike Smith, Raven Industries_)]
The three pilots, Kittinger, Kaufman and Fulgham, flew training missions together. Kaufman and Fulgham alternately flew the balloon while Kittinger instructed. The missions were flown at night to take advantage of light winds and avoid the effects of diurnal heating on the helium (the lifting gas that filled the balloon). Used for these missions were 30-foot diameter polyethylene balloons and an aluminum gondola especially designed for low altitude training.
The first training mission scheduled for May 19, 1959 was canceled due to equipment problems.[173] Problems overcome, the next day at 1:30 a.m. the mission launched from White Sands Proving Ground.[174] The objective of this flight was to practice gas valving and ballasting techniques necessary for balloon control and to practice landings. After a five-hour flight, the balloon landed without incident just after sunrise northwest of El Paso, Texas.[175]
