Dear Lsson;
Here are the comments on the recent batch of material. A few cases are
certainly of considerable interest. Over all, in this batch, Venus counts for only
one: 28 January, Stuttgart. Fireballs most probab cases; balloons
for four and aireraft for three.
Coming to the interesting casest the Korean 20 April should certainly
be followed up. This comes cery close eto being a security-Intelligence matter. I'd
certainly like to get more information on this How about sending a few Form A's to
Korea. Actually, this should have been investigated on the spot by Intelligence
officers.
May: This has same similarities to orman
cas needed and Form led out on this. .
San Antonia 7 May: This has many similarities to the Lubbock Lights
Finally,
would help.
hope you will concurr.
And keep 'em coming. It's easier t equently
than a larger batch at longer intervals.
send her regards. :
