Flight 85: Released at Alamogordo, New Mexico, 1542 MST, August 17, 1948 Not recovered
The objective of this flight was to carry a standard radiosonde to a high level; there it was to be released on a parachute and, at the moment of release, the batteries for the transmitter were to be activated. To accomplish this a pressure-triggered switch was rigged on a .001", 20-foot polyethylene balloon. Below the baroswitch a standard T-69 radiosonde was supported with a parachute stuffed into a case also hanging from the parent balloon (Figure 36). Two plugs were set to keep the transmitter circuit

open until the baroswitch fired the "cannon" which severed the supporting line. Then the circuit plugs were to be pulled from their stops, and the parachute was to be pulled from its sock, supporting the radiosonde on its descent.
The failure of this system to act may be attributed to the use of a squib to fire the line-cutter cannon. Subsequent tests at lower levels (where the squibs work better) were made with a satisfactory release and activation of the "dropsonde."
