Fligl\t 106: Released fran Alamogordo, New Mexico, 0657 M.ST, February a. 1949
Recovered at Ellsmore, Kansas
1'his was the first .flight to clearly demonstrate the e.f.ficieilt action
ot a combination ballast control--displacement switch and rate-or-ascent
nitch--on a 2o-toot, .001• polyethylene balloon. From the height-time curve
and ballast-flaw record (Figure 54), it will be seen that the ballast con-
trol waa operating at 41,000 teet USL during the period or radio reception
from Alamogordo, New Mexico. By the time the second receiving station picked
up the signal, all of the ballast had been exhausted and the balloon was
falling. On this flight a high loss of lifting gas caused the total ballast
load ot 600 g~s to be exhausted in leas than .five hours. (Average used in
first two hours was 1700 grams per hour.)
