The
czp on the first nose cone was still intact, probably due to a short in the

When recovered, the nose cone contained abcut 60 ml,
At H / 9 hours the filter of this nose cone read about 1 mr./hbre

The third nose cone was from a rocket programmed to

About 100 ml, of water had leaked into it, and the

After
this shot, an intensive effort was made to determine the c2use of leakage
of water into the nose cones,
It was found that the ball joint sezling the
forward end of the nose cons efter sampling could beunce back 2 small
zmount after closure, thereby permitting water to enter,
<A Istching
mechanism was designed to lock the ball joint in its totally clcsed position.
This modification was then zepplied to all nose cones,
