We appreciate any assistance that can be given.

No other launches '\vould acco t ~or observation . He had been up in Canda at this time and had heard of not~ing unusual up thereo He said it would be unlikely that any of their bnlloo~s would be responsible for they normally don't get across the Hudson Bay bef~=-e going west-w-ard. Also said that there were numerous radiosonde l aunche s in Ca.r:a=.a that launch dally c.nd that our weather man should be/help us in this N:. , Bo~der, Colorado reported negative results. he did ~ot know of any ba!loons to account for the Dr. 1-lorris observence Lt. Marley, I have revie,.red this sight ins and it seems to fit the description of a balloon launched from Ft. Churchill. However, other stations within a 500 n9utical mile radius of the sighting also launch radiosonde balloons whi ch tend to fitthis description as outlined here by Mr. Noble. Tne only way I know to confirm or at least try to confirm the track of th~se balloons is to request the weather data for the specific launch If you feel that this extra effort is desirable then I will initiate the neccsss.r:r action acquire the data. Sometimes weather balloons will develop a leak, as a result they ne.-~r reach high alti:t:..lde or their normal size. This could be the case iL this instance. However, since ocviously no national threat is indicated and no sc~e~tific benefi~ b e gained, I suggest that the expenditure of t he extra manhours a::::: computer times to reti~ieve this data would not be t1stified. { s) tiJtlj &ni th
