ithe reason for making free-air pressure measurements, Hlunda
replied that‘this is just about a routine measurement with then, in other
words, they féé]}that in the indefinite future they should get this at
every opportunity they can.
If there is an operational reason on same
particular shot’for not making these, they might be willing to give a point.
It was agreed! that the object is to get in the state where one can
predict with the accpracy desired. However, they do not think they are in
that state yet, for-hi'gh-yjeld weapons.
