IR-77-53 — 1953-12-09 — 8 miles northwest of Thule Air Base, Greenland

On 9 December 1953 at approximately 0922Z, Lt James N. Hendon (pilot) and Lt Walter O. Rich (radar observer) of the 318th Fighter Interceptor Squadron observed an unidentified object during an airborne training mission. Their F-94 was at 2,500 ft altitude, heading 340 degrees at 200 knots, 8 miles NW of Thule Air Base. The object was a green light at the same altitude as the observer aircraft, 1-1.5 miles away at azimuth 120 degrees starboard, paralleling the aircraft straight and level at ~400 knots. It went out with no fade at azimuth 020 degrees starboard. Observed by Hendon 5-7 seconds, Rich 2 seconds. No interception attempted; no radar contact established. Other traffic: one F-94 6 mi west and one C-47 12 mi west. Both observers said it was not a meteor. Preparing officer evaluated as probably astronomical phenomenon.
