An aircraft engaged in a bombing mission exploded mid-flight over Lake Upemba, resulting in the deaths of everyone on board.

What happened

During a military mission originating from Manono, an aircraft experienced a catastrophic event while traversing the airspace above Lake Upemba. Shortly after beginning its flight path for a bombing operation, the plane underwent an in-flight explosion. The aircraft subsequently descended into the waters of the lake.

There were three fatalities recorded in the accident, as there were no survivors among the crew members on board at the time of the crash.

Findings

Preliminary investigations suggest that the destruction of the aircraft was triggered by an internal detonation. It is believed that ammunition located within the cabin ignited while the plane was still in flight, leading to the mid-air breakup and subsequent impact with the water.

Probable cause

The accidental detonation of ammunition stored inside the aircraft cabin during flight.
