Project 10073 Record Card — Edmonton, Alberta, 19 June 1959

This document consists of a Project 10073 record card and associated correspondence regarding an unidentified aerial phenomenon reported on 19 June 1959. The sighting occurred at 0430Z in the vicinity of Edmonton, Alberta, Canada. Two witnesses observed a single, cigar-shaped object that was reddish-brown in color. The object was estimated to be the size of a small flock of ducks and was observed through 7x binoculars. The witnesses reported that the object rose vertically from just below the horizon against a background of sea ice, reaching an elevation of 40-50 degrees. The observation lasted for approximately four minutes. Weather conditions at the time included six miles of visibility, one-tenth cloud cover, and a ceiling of 7,000 feet, with a small fog bank located six to seven miles offshore to the north. The report was initially delayed due to improper addressing by the 4601st Support Group, which was subsequently advised on correct reporting procedures by the Air Defense Command. F/O LK Neilson, the duty operations officer, reviewed the report and concluded that there was no plausible explanation for the sighting. The official conclusion recorded on the card states that no logical conclusion was reached and the case was considered unidentified.
