Dear Lt. Olsson; This is a belated report on the last batch tmich I received at the end ot April. Just as soon as our plans tor employing ~.!iss officially co throur,h, I shP.ll be able to send you a sheet vr1 th .ern each individual c:lse, so that you lrl.ll have my conunents on each folder. The lettor method xx has obvious dr:.\\rbacks. But until that time comes and she c~.n handl~ my typine and co~plP.tion or forms, I hnd better stick to this lett~r method. In this latest batch \'/O have only 4 really interesting cases. I rni ht r.1ention a ~th, 28 l arch 53, Scott AFD, Vihich is the 1st rnport I ve seen of an honest to coodness mir~c:e. 6 Cases have only one observer and I'M following my usual rule or discountinr. those. 8 April was a met r--. Tho .. Great F'all. J.pri case was Venus if reported timep ,;as in 28 lfa.rch :~lbrook AFB wan prjobably Venus. 31 !'arch J10:-.shu, and 30 lfarch Lyle, Y!ash., are puzzling but could pos3ibly have been balloons ~p~il areenlund case nas an obvious meteor. This brings-us to the interestinc cases: . 2) !.!arch 5an Antonia could hardly have been a mirage and I m surprised there was no radnr pickup. as there any aircraft like helicopters that rn1{lt explain this. Anyth:tn6 more come in on this one? Don t th.i1k this is cood enou~h for a pinch-bottle but it should be listed as Uocturnal ;.1eanderinr, ll:lcht 29 Harch Spooner, '''isca Duration times needs ch3cking here . H~:td to to bolievo th~t object could h3Va done 11 that in 1$ secondn. An ~nterasting case and one or the regul~r question9~ea should be sent to it.r. Gilette. Ne~"t is the 12 April S._tead AFB. I think this is the most int~resting cast) or the batch, and I hope you receive more dope on it. Questionalres mould be sent.I d like to see l.!enzP-1 .explain this one 1 Is there any possibility thatt.he:~o could hava been airc.~:t)t? Appapmtly ducks have been eli:ninated. /'\ ....
