large area, gave rise to waves which went clear around the earth and re-

bounded several times.

As for the objectives of such studies:
{t is conceivable that
they may have some practical use in the future, e.g., remote detection,
knocking aircraft or missiles out of the sky--but at the moment, the primary
point of such a measurement would be just to study the waves.
If balloons are to be used, they must be ordered in the very near
future. Telemetering methods and equipment must also be looked into, and a
requirement will exist for communications, at least of the same order as
Cox's microbarographic stations. Zadina was doubtful that J-10 could take

on this measurement and suggested AFOAT be asked to do it.

He pointed out that

it requires someone to find an instrument to measure the phenomena which
White says will occur, a balloon expert, telemetering equipment and channels,
ete. Porzel agreed that this is Frolich’s Greenhouse experiment ten times
over.

Aamodt suggested a possible method: looking st the ionosphere.
Watt thought this could be quite useful, since that layer will certainly have
been disturbed, and presumably it could be observed at a reasonably
late
time. Whitener suggested visiting at White Sands or Inyokern to ask them
about their equipment and methods of detection.
The subject obviously needs more study before instruments or stations

can be chosen. In the meantime, J-10 was asked to look into (a) balloons,
(b) telemetering, and (c) methods of observing the ionosphere.
