Correspondence regarding geological specimen analysis and UAP report

This document contains correspondence and a completed U.S. Air Force Technical Information questionnaire regarding a reported sighting of an unidentified aerial phenomenon in Aberdeen, Maryland. The witness, a 71-year-old male, reported seeing a 'ball of fire' approximately 6 feet in diameter that descended 30 to 40 feet off the road, hit the ground, and burst. The witness subsequently sent a sample of the material he believed was left behind to the American Geological Institute. The material was forwarded to Dr. E. H. T. Whitten at Northwestern University for analysis. Dr. Whitten concluded in a memorandum to Professor J. Allen Hynek that the specimen was not a UFO, but rather a piece of metamorphosed quartzite of likely local origin. Dr. Whitten noted that the information provided by the witness regarding the location of the find was 'scant' and recommended that the Air Force require informants to provide more precise location data, such as sketch maps, to assist investigation teams. The document also includes a letter from Major Hector Quintanilla, Jr., Chief of Project Blue Book, dated June 13, 1966, informing the witness that his initial report was insufficient for evaluation and requesting he complete the attached FTD Form 164.
