Incident #37 Sighting Report — Phoenix, Arizona, 14 October 1947

This document details Incident #37, a sighting that occurred on 14 October 1947, approximately eleven miles north-northeast of Cave Creek, Arizona. Two mine operators, both of whom were experienced pilots, observed a single object traveling from the northwest to the southeast. The object was reported to be at an altitude of 8,000 to 10,000 feet, moving at a speed of 350 mph. The witnesses described the object as having a diameter of approximately three feet and noted that it resembled a 'flying wing.' Its color was reported as reddish against the blue sky and black against white clouds. The observation lasted between 45 seconds and one minute, with no sound reported. The report includes an evaluation by the Air Materiel Command, which expresses skepticism regarding the account. The investigators noted that the witnesses provided conflicting remarks, with one observer initially suggesting the object was a buzzard before changing their mind. Furthermore, the AMC concluded that if the object were truly 10,000 feet away and appeared only three feet wide, it would have to be an enormous object, a contradiction that the investigators felt discredited the report. The document also includes index lists from the Project Grudge report, categorizing various incidents by their nature, such as astronomical, balloons, aircraft, or those lacking sufficient evidence for explanation. The final assessment for Incident #37 is that there is nothing astronomical about the event and the provided information does not suggest any other plausible explanation.
