Incident #147 Sighting Report — Springfield, Ohio, 27 July 1948

This document contains a military intelligence report regarding a sighting of an unconventional aircraft, designated as Incident #147, which occurred in Springfield, Ohio, on 27 July 1948. The report was forwarded by Captain Dwight L. Boyd of the Headquarters Second Army to the Director of Intelligence at the Department of the Army. The primary witness was a female civilian who observed a round, 'huge ball' object moving north at a 'great' altitude. The witness reported that the object possessed a 'bright red tail of fire' and traveled in a straight line at a speed comparable to a jet. The observation lasted for approximately three seconds. The official evaluation, extracted from the Project Grudge report, concludes that the description is consistent with a fireball or a bright meteor. The report suggests that the object was likely a meteor crossing the earth's orbit toward the sun at the time of the collision. The document includes references to previous correspondence regarding unconventional aircraft and mentions enclosures containing agent reports involving individuals named Gibson and Henry. Additionally, the document includes an index of Dr. Hynek's evaluations from the Project Grudge report, which categorizes various incidents by their astronomical probability or other potential explanations.
