Object appeared to be 100¬-150¬ between intermittent bands, which equaled the length of the object, followed its disappearance behind clouds. Lambert Conformal Conic Projection Standard Parallels 7° and 50° Scale 1:1,000,000 (731) STATUTE MILES XH30 A YH QB 70 AAY Transcribing the text in the document: AIR INTELLIGENCE INFORMATION REPORT SUBJECT: Unidentified flying object, Guam, M.I. Sqdn. reported that they sighted an unidentifiable object traveling at an approximate heading of 270 degrees at an estimated speed considerably in excess of that of a conventional jet aircraft. There was no exhaust or vapor trail observed. A similar or the same object was observed by two pilots of a B-17 at approximately 100 miles from Guam on a heading approximately 270 degrees during the same time span as the original sighting from the ground. There appears to be no reason to doubt the validity of the observers' claims of sighting a flying object. Although the ground observers have not been trained in aircraft identification, the two pilots have had considerable experience and stated the object sighted did not appear to be a conventional type aircraft to their knowledge. 1952 while enroute from Kadena to Anderson AFB, Guam in an R-47G, as the pilot, I was flying in the left hand seat. We were flying at 7000 feet and the object appeared to be at about 5000 or 6000 ft. The object was easily discernible to me when first sighted but only remained in view for approximately 20-30 seconds. MCKOWN MAJOR, USAF On the 19 december 1952 approximately 6:30 p.m. there was flying at 7,400 feet an unidentifiable object of 150 degrees in view a few AY Engines traveling about 20 degrees to our course and approximately the same altitade. This object was in my sight for several seconds before it passed into a cloud.
