Project 10073 Record Card — St. Paul, Minnesota, August 9, 1952

This document is an Air Intelligence Information Report regarding a UFO sighting in St. Paul, Minnesota, on August 9, 1952. The report includes a Project 10073 record card, a formal transmittal letter from the 31st Air Division, and a detailed observer questionnaire completed by a 43-year-old Abrasive Research Engineer. The witness reported observing an elliptical, silver or aluminum-colored object that resembled a jet aircraft but lacked wings. The object was seen moving from the southeast to the northwest at a high speed, estimated by the witness to be approximately 1080 miles per hour, before vanishing abruptly after 10 to 15 seconds of observation. The witness noted that the object was completely noiseless. The report includes a hand-drawn sketch by the witness illustrating the path of the object and its appearance relative to the horizon and local landmarks. The witness also mentioned that they had contacted the 'Denol Mills Research Laboratory' to inquire about potential balloon activity in the area, but were told none were present. The witness expressed a firm belief that the object was a mechanical device, noting that they had seen many meteors and other aerial phenomena in their life, but nothing like this. The report was forwarded by the 31st Air Division to the Air Technical Intelligence Center at Wright-Patterson Air Force Base in accordance with AFL 200-5.
