Flight 81: Released from Alamogordo, N6W Mexico, 0548 MST, August 6, 1948
Not rec.overed
The balloon flown on this flight was made of .004" polyethylene, and it
was eggplant shape about 20 feet in diameter and 25 .feet long. The first o.f'
its kind, this balloon was made by Goodyear Tire & Rubber Company, Inc.
Only a short period o.f' radio reception was obtained, but during this time
the balloon rose with predicted speed (500 feet per minute) nearly to its
predicted altitude (40,000 .feet) and floated within 1500 feet of the 37,000-
.f'oot level. Figure 34 is the height-time curve for this flight.

Figure 34
Since the balloon ttid not descend far enough below its maximum altitude
to activate the minimum-pressure switch and the automatic ballast valve, no
ballast flow data was telemetered wnile the balloon was within the radio
range. This indicates a verJ low rate o.f' gas loss through the walls of this
balloon.
