There is an odd-looking structure near NAF El Centro

(http://members.cox.net/rtbachman/mystery.htm)


that appears to be some sort of centrifuge. The PAO
says that it was somehow used to test parachutes.


Does anybody know how the testing was performed? It
is hard to believe that this thing just swung a loaded
parachute around in a circle. You could do the same
thing with a crane and a weight.
