SECRET. SUMMARY While there are approximately 375 incidents on record, only in= cidents Nos. 1 thru 2h are encompassed in this report. Of the later incidents, many have not yet been investigated, few have been completely tabulated, and none have been submitted to the consulting agencies. It is certain that better over-all results will be obtained in the analy~ sis of the later reports, as these incidents generally have been more completely investigated, Since 5 December 19)%, a series of recurring phenomena described as "green fireballs" have been reported in the general vicinity of Al- buquerque, } lew liexico. Mr. Lincoln La Paz, noted meteoritic expert, has been oer? though unofficially, associated with the investiga- tion of thes e sightings and has himself observed the phenomena. rr. La Paz states he is convinced the creen fireballs are not ordinary meteors. This group of incidents has little or nothing in common with other i cidents on file with Project "Grudge", therefore, these incicents are not considered in this report. The Scientific Advisory Committee was asked to investigate this matter and had advised that an independant investigation be conducted in the field of atmospheric research. Upon eliminating several additional incidents due to vagueness and duplication, there remain 22¢ incidents which are considered in this report. ‘thirty of these could not be explained, because there was found to be insufficient evidence on which to base a conclusion. Consulting agencies provided plausible sclutions for 16h incidents, along with the following comments and “indines: - eo Rand Inc. — (172 f2 Incidents considered) "Ye have found nothing wiich would seriously controvert simple rational explanations of the various phenomena in terms of balloons, conventional aircraft, planets, meteors, bits of paper, ee tllusions, practical jokers, psycho- pathological reporters, and the like." Chio State University (Dr. Hynek = 21); Incidents considered) Assuming evidences of observers and investigators to be correct, Hynek concluded that 32% could be explained astronomically, 35% Spr be attributed to balloons, aircraft, rockets, birds, etc., and 33 ither lacked necessary evidence or a suitable explanation was not ee When due allowance was made for inaccuracies in observing and reporting, 53% mizht be explained astronomically. Air “eather Service (233 Incidents considered) 12.0% apparently were weather balloons. iv Cab y ye j | ad | % denen Declassification Authority: NND 57565
