AI-Generated Summary
A radar sighting at West Mesa AFS on 26 November 1957 recorded an object moving at 3000 knots. The military concluded the track was caused by anomalous propagation.
This document consists of a Project 10073 record card and associated military teletype communications regarding an unidentified radar track observed on 26 November 1957. Personnel at the 687th AC&W Squadron at West Mesa AFS, New Mexico, reported a radar blip moving at an estimated speed of 3000 knots. The object was tracked for 1 minute and 24 seconds using an MPS-7 radar system. The report notes that the blip was observed at an azimuth of 315 degrees and a range of 170 miles, with an altitude of 35,000 feet. Witnesses identified in the report include A/3C Scott, Bazinette, and A/2C Montoya. The official conclusion reached by the evaluating authorities was that the radar return was not indicative of a physical aircraft or astronomical phenomenon, but rather the result of anomalous propagation. A handwritten note on the document suggests a lack of familiarity among some personnel regarding the specific characteristics and limitations of the radar equipment used during the incident.
Since no confirming evidence was presented, it is assumed that anomalous propagation of some sort caused the reported track.
