The peint is, tliat we
con't have direct evidence for diffusion rates in the stratosphere
yet, and we could get evidence if we could get balloons up through
tae cloud and track it for even a few days, as is stgested here.

So far, I think
the only real objection which has heen raised is that there
might be sone otherway of doing 1 more economically, because
the idea of a large network of balleen: soundings 1a rather horrifying, in a way, until one compares it % the cost of Mying
aircraft, «hich would have to be jet aircraft, ap to theve sans

people will object to the fact that we are trying to teleneter
the information back and are not making an atteapt te find out
what the material ta lile.
It ia, in principle, perfectly possible to recever samiles fron
balloons; that is, to send sampling gear up on a balloon.
Weights as mch as a ton have been carried hy General Hillis
polyethylene balloons up to 90,000 feet. We'd like to go
higher.
“ea could, presumably, if you want te cut down on the
weight to a few bundred poundas we could get up te a 100,900 feet
with these big balloons.
Therefore it does suggest that if we
wanted to find out what sort of zaterial is in the stratosphere
one could also use balloons in this case. First of all, getting
