Just as soon as our plans for employing Miss officially
go through, I shall be able to send you a sheet with comments on each individual
case, so that you will have my comments on each folder. The letter method in
has obvious drawbacks. But until that time e comes and she can handle my typing
and completi had better stick to this letter method.
In this latest batch we have only 4 really interesting cases. I
might mention a 5th, 28 March 53, Scott AFB, which is the lst report I've
seen of an honest to goodness mirage. 6 Cases have only one observer and I'M
following my usual rule of discounting those.
meteor.-
The Great Falls 3 April case was Venus if
error.
28 March Albrook AFB was prjob Venus.
and 30 March Lyle,
possibly have been balloons.
The 8-April Greenland case was an obvious meteor.
This brings us to the interesting cases:
25 March San Antonia could hardly have been a mirage and I'm surprised
there was no radar pickup. Was there any aircraft like helicopters that miht
explain this. Anything more come in on this one? Don't think this is good enough
for a pinch-bottle but it should be listed as Nocturnal meandering Kight.
29 March Spooner, "isc: Duration times needs ch@cking here Head to
to believe that object coul ve done that in 15 seconds.
and one of the regular questiongries should be sent to lir. Gilette.
Next is the 12 A April Stead AFB
case of the batch, and I hope you receive more dope Questionaires sbould be
sent.I'd like to see Menzel explain this one! Is there any possibility thatthese could
have been aircraft? pparently ducks have been eliminated.
As for-the 26 Mabch, Equasseur AFB although NL, the data are ncon-
tradictroy nsufficient. Perhaps this was a helicopter? We ought to ke have
much more information on this one Has this been received?
