Flight lOa Relea1edtrom Alamogordo, New Mexico, 0601 MST, July 6, 1947
Not recovered
!hie flight wa1 the first to use a large plastic balloon as the lifting
vehicle. !he oell was spherical, 16 teet in diameter, and the walls were
.ooa• polyethylene heat sealed at the seams (made by Harold A. Smith, Inc.).
1he altitude control was an automatic ballast valve, pressure-triggered to
throw ott liquid ballast. !he equipment train used on this flight is shown
in Figure 5.
