Multi-aircraft Event — United States Air Force USAF 53-3222 / United States Air Force USAF 53-7841

Two United States Air Force Fairchild C-119G Flying Boxcars collided in mid-air near Altensteig after one aircraft suffered an engine failure during a formation flight. The stricken aircraft lost altitude before abruptly climbing into another aircraft in the formation. Both aircraft crashed in a wooded area, resulting in the deaths of all 66 personnel on board both planes.

Investigation Summary

The accident involved a formation of three C-119G Flying Boxcars from the 60th Troop-Carrier Wing, which had recently departed from Stuttgart. Shortly after 14:00, the aircraft positioned on the right side of the formation experienced engine trouble at approximately 4,000 feet. This mechanical failure caused the aircraft to lose height initially. In an attempt to recover or due to aerodynamic instability, the aircraft then climbed sharply, striking the second aircraft in the formation. The collision caused the first aircraft (53-7841) to disintegrate immediately, while the second (53-3222) remained airborne for a short period before crashing into a forest approximately 30 miles from Stuttgart.

Final Conclusions

The collision was triggered by a mechanical engine failure on one of the formation aircraft. The subsequent loss of control or erratic flight path of the disabled aircraft led to an unavoidable impact with its wingman. The intensity of the post-crash fires in the wooded terrain hampered initial rescue efforts, though it was quickly determined there were no survivors.
