Incident
A Mercurius aircraft, accompanied by two other similar aircraft, was performing a local demonstration flight as part of an airshow at Cape Town Airport. The formation executed a low pass over the airport and then proceeded westward. Shortly thereafter, all three aircraft simultaneously struck the slope of Devil's Peak, a location approximately 15 kilometers west of Cape Town Airport. The mountain slope was shrouded in clouds at the time of the impact. All three aircraft were totally destroyed, and all 11 crew members on board were killed.
Investigation
The official investigation into the accident determined the probable cause to be controlled flight into terrain, indicating that the aircraft were under pilot control at the time of impact but flew into terrain unintentionally due to the obscured conditions.
