B-47 Stratojet emergency landing in Greenland after navigation loss (45-21768)

Thule AFB (Pituffik), GreenlandFlight

On February 21, 1947, a Boeing B-29 Superfortress (registration 45-21768) operated by United States Army Air Forces - USAAF (1941-1947) was involved in an aviation accident near Thule AFB (Pituffik), Greenland in flight. No fatalities were reported. Investigators recorded the probable cause as: The emergency landing was necessitated by the loss of navigation orientation due to poor weather conditions and critically low fuel reserves. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 8 related events involving the same aircraft type or operator are linked below.

A crew of eleven lost orientation over Greenland during a top-secret mission and executed an emergency landing on ice near Thule Airbase. The aircraft was later destroyed by fire in 1995, while the crew survived.

What happened

The aircraft departed Fort Wainwright (Ladd Field) on a classified reconnaissance mission intended to last between twelve and twenty hours. During the return leg, while flying over Greenland at an altitude of 24,000 feet, the crew encountered deteriorating weather conditions that resulted in a loss of situational awareness. The pilot was unable to determine the aircraft's exact position and reported to base that fuel reserves were critically low, with only four minutes remaining.

Consequently, the crew initiated an emergency landing procedure. The aircraft made contact with an icy surface located approximately 280 nautical miles north of Thule Airbase. All personnel on board survived the impact. Rescue teams reached the site three days after the incident and evacuated the crew. The airframe, which had been designated "Kee Bird," was left at the crash site.

Findings

In the 1990s, a recovery team was assembled to retrieve the wreckage from the remote location. However, on May 21, 1995, a fuel leak caused the abandoned aircraft to catch fire. The resulting blaze completely destroyed the remaining structure of the plane.

Probable cause

The emergency landing was necessitated by the loss of navigation orientation due to poor weather conditions and critically low fuel reserves.
