Project 10073 Record Card — Goose Bay, Labrador, 23 March 1956

On 23 March 1956, at 1039Z, a military flight crew operating at 30,500 feet on a heading of 070 degrees observed an unidentified object. Approximately four minutes after leveling off, the crew spotted the object at their ten o'clock position. The object approached from the east, and the observers quickly realized it was not an ordinary aircraft. It appeared to be 2-3 miles to the left of the aircraft and 2,000 to 5,000 feet above. The object passed from the nine o'clock position and disappeared from view at approximately the seven o'clock position. Both the pilot and co-pilot observed the object for approximately 60 seconds until it disappeared behind their aircraft. They estimated its speed to be between 500 and 600 knots. The object was described as round, blue in color, and trailing heavy yellow-orange fire and sparks. Its overall silhouette was described as a teardrop shape, and it was moving in level flight. One observer compared the object to a V-2 rocket seen during World War II, while the co-pilot noted that as it moved away, it looked like the tailpipe of a jet. The official evaluation of the incident, recorded on a Project 10073 record card, concluded that the object was a jet aircraft, noting that the duration of the sighting was considered excessive for a meteor.
