Witnesses on the ground outside Lusaka watched the 707 finish its approach turn in the bright morning sun. It was flying the last leg of a three-leg cargo run that had begun the previous evening at London Heathrow and was almost over. Then, without warning, they saw the entire right horizontal stabilizer and elevator assembly come away from the aircraft. The 707 lost pitch control from about 800 feet. What happened next took perhaps eight seconds. It ended in a field of wreckage about 12,010 feet from the runway, with all six people on board dead.

Registered G-BEBP, it had entered service with Pan American World Airways in 1963 as Pan Am's first convertible 707, built so the cabin could be reconfigured between passenger and cargo roles....

Coordinates 15.33°S, 28.40°E (Lusaka, Zambia - Kenneth Kaunda International Airport, FLKK/LUN, formerly Lusaka International). Recommended viewing altitude is the normal approach profile to runway 10: cleared from FL110 through 6,000 ft to a visual approach. Field elevation approximately 3,780 ft MSL. The crash site was approximately 12,010 ft short of the runway threshold on the approach path. Expect high-density-altitude operations, occasional dust, and clear winter (June-August) conditions.

A 707 without a functioning horizontal tail is not a glider - it is a falling building. From roughly 800 feet above the ground, the nose pitched over and the aircraft entered a dive that it could not arre...

Flight International devoted articles in October 1977 and June 1979 to the broader question the Lusaka accident had made unavoidable: what happens to airliner airframes that stay in service for decades, accum...
