Flight 110: Released from Alamogordo, New Mexico, 0649 MST, February 11, 1949 Recovered at Kershaw, South Carolina
This flight had as its main objectives the testing of a Winzen Research Inc. .0015", 20-foot polyethylene balloon, and further testing of the combination ballast control-displacement switch and rate-of-ascent switch. Following the initial ascent of this flight, a slow descent resulted from loss of lifting gas. Three hours were required for a descent of 2000 feet to the pressure where ballast flow was begun. This and the general flight pattern indicate the satisfactory nature of this Winzen Research Inc. balloon. After ballast started, the valve stuck and a constant flow at 1800 grams per hour followed. The rising ceiling seen in Figure 56 is the typical flight pattern for a balloon whose load is being steadily decreased at a rate in excess of the loss of buoyancy.

On this flight all three of the receiving stations positioned along the expected path were able to receive and record the pressure and ballast signal. No temperature equipment was flown.
