Balloon launched on: 8/19/1976
Launch site: Yorkton, Saskatchewan, Canada
Balloon launched by: SED Systems Ltd. (Saskatoon)
Balloon manufacturer/size/composition: Zero Pressure Balloon 300.000 m3
End of flight (L for landing time, W for last contact, otherwise termination time): 8/19/1976
Upon launch, the balloon suffered a large tear near the bottom that allowed ingestion of a considerable quantity of near-surface air likely rich in gases from support and launch vehicle exhausts. Consequently expulsion of this trapped air as the balloon ascended may have perturbed the ascent data
