PROFESSOR MOORE - 6/8/94
A: The ones in early June were all service flights. In
other words, all flights we were making for Peoples, and we had
some radar test flights.
Q: so to go with the June 14th date, what type of flight
do you think would have ..•
51
A: All the balloons launched in that period would have
been meteorological balloons, 350 gram meteorological balloons,
some of them with radar targets just to test the radar out and
some of them, I'd forgotten all about it, but Crary's diary says
we had sonobuoy microphones on some of them. So that black box
that Cavitt had really began to get my attention.
Q: That would not be a radiosonde.
A: That would not be a radiosonde.
Q: What would a radiosonde look like?
A: It would be a white, usually a cardboard or a plastic
box, and the fact that we were involved in radar is because we
weren't allowed to have our radiosonde equipment. We weren't all
set up for that.
Q: You said you didn't bring it with you.
A: We didn't bring the receiver. I have to correct
myself, we did attach radiosondes to them, to the flights
carrying microphones because there's a statement in this summary
here of radiosonde reception. Radiosonde recording. So I take
that back. Yes, we had radiosonde. But we did fly this one
mentioned here, on June 4th, out to Tulerosa range, no balloon
flight, again, on account of clouds. By that he means none of
their flights. Then "Flew regular sonobuoy mike on a cluster of
balloons and had good (inaudible) receiver on ground but poor on
plane."
Q: I notice early on you were going ahead with the Navy
stocked sonobuoy while Professor Ewing was trying to perfect his
technique of the low range frequency microphone.
A: Oh, the low frequency microphone, right. That's
correct.
Q: He was experimenting with both AM and FM, is that your
recollection?
A: In the laboratory, devices for measuring low frequency
acoustic waves were well known, but what he was attempting to do
was to modify these and devise something to be a throw-away
microphone and radio transmitter, so this was to build an
instrument for a certain purpose. He actually had a fellow named
