The writer therefore wishes to make the :rollow1ng reco11:1?1endationa,
(6. 1) That e.rraneements be made tor dust collections on airplane 'flights
at altitudes or 40,000 tt. or oore through ~he regton ot the atcloaphera lying
beneath the real puthil ot green fireballs as soon as possible after the occurrence
ot s~h fireball 1nc1denta.
Such arrangements preeupposo a wll coordinated
observing network pertlitt1ng t:te epeed1eet possible determination ot the looation
or the real pathl"I in the atnosphere.
(Dr. Crozier and Mr. $eely have both agreed
to cooperate in carrying out dust colleotion at the htghest altitudes attainabla.
In Dr. Crozier' s opinion, a B- 36 or
50 should be made available tar such work. )

5:!lat crOUJ1d- level dust oollect1ons be made along tho well deter­
mined earth- traee or the green fireball of 1anuary 30th, using the portable impaet­
.ment equiptBnt al.reo.dy rigged up by nr. Crozier and ur. Seely and used in the e;round
searches ot J'uly 27th and ~ust 8• 9th. I:r copper particles can be recovered
along this carth..tro.ee but do no, appear in colleotions made 50 miles or eo et1ey
trm the trace , the z,eault -=,ul.d be ot much signiticmoe if not indeed deeisivo.
