turns out now, that Pete Hyckoff tells us that the Air Force

A few flights have been nade which
show that the instrument is practical and, presumably--if
Y oa queting you right-—it could be done between 2100 and
$200 per instrument, or something in that region, if one
wanted to produce a lot of these.
The radiosonde network already provides a large muber of
telemetering stations. It also provides erews for launching
baliocns.
This is an attractive idea, practically, vecause
4% means one does not have te set up the ballcon-launching
network--it's already there; one would merely tie on extra
equipment when one wanted to try this experinent.
The question of how long we can track the aloud using
eonductivity measurements cams up yesterday, and none of
ws was quick enough to make the calculations in our heads;
however, I figured from what was said yesterday, that apparently the rate of creation of ione by cosmia raya in the region
