Project 10073 Record Card — Grand Marais, Minnesota, 18 February 1956

On 18 February 1956, at approximately 0142Z, a ground observer named Lila Hall reported an unidentified aerial phenomenon near Grand Marais, Minnesota. The witness, whose reliability was assessed as excellent, described a single object shaped like a pumpkin with white and blue coloration. The object was observed for a duration of three to four seconds before it appeared to land in Lake Superior. The sighting was reported via teletype from the 739th AC&W Squadron in Wadena, Minnesota, to the Air Defense Command at Ent AFB, Colorado, with information copies sent to the Air Technical Intelligence Center at Wright-Patterson AFB and the 31st Air Division in St. Paul. The official record card for Project 10073 classifies the event as an astronomical meteor. However, the teletype report includes a note from 1/Lt. Edgar F. Pierce, who suggested the possibility that the object could have been weather balloons launched from Duluth (DLH). The report confirms that no photographs were taken and no radar contact was established. The weather conditions at the time were noted as 'not riven'.
