Circumstances:
The DC-10 departed N'Djamena Airport at 1313LT bound for Paris-Roissy-Charles de Gaulle Airport. Forty-six minutes later, while cruising at an altitude of 35,000 feet over Niger, the aircraft disappeared from radar screens and the crew did not send any distress call. It was quickly understood that the aircraft exploded in mid-air and crashed somewhere in the desert. SAR operations were initiated and the wreckage was found a day later in the Ténéré Desert, about 650 km north of N'Djamena, northeast from the Termit Mountain Range. Debris scattered on 100 km2 and none of the 170 occupants survived the crash.
Probable cause:
It was determined that the accident was the aircraft was destroyed by an explosion. The following findings were reported:
- The destruction was due to an explosive charge placed in a container located in position 13R in the forward cargo hold.
- The bomb was formed of pentrite, namely an explosive composed with a powerful and very sensitive crystalline nitric ester.
- The Investigation Commission assert that the most plausible hypothesis is that the explosive charge was inside baggage loaded at Brazzaville Airport.
- Observations made shortly after the accident on Brazzaville Airport made it clear that, at that time, the airport security measures in force were not in accordance with the ICAO standards and recommended practices (Annex 17 to the Convention on International Civil Aviation and Civil Aviation Security Manual (DOC 8973)).

Circumstances:
During the night cross country flight at FL250, the pilot elected to leave the cockpit area and move to the rear of the aircraft to attend to physiological needs. Although oxygen was available in the cockpit, supplemental oxygen was not available in the rear. The aircraft was operated with a known pressurization system deficiency which limited the airplane to flight to 17,000 feet msl while maintaining a cabin altitude of 10,000 feet. After 2 hours and 10 minutes, atc declared the flight to be 'no radio'. At 3 hours and 57 minutes after departure, the airplane was plotted on radar in a descending left turn to ground impact. Fuel starvation resulted in power loss to the left engine. Propeller signatures indicated power on the right propeller at impact. The pilot's body was found in the aft cabin area on the aft cabin bulkhead.
Probable cause:
The pilot's poor judgement and the resultant hypoxia sustained in the unpressurized airplane. Factors were: the malfunctioning pressurization system and the pilot's decision to continue operation with that known discrepancy.

Circumstances:
At approximately 3:00 p.m. on September 10, 1987, the Army called Black Hills Aviation to suppress a fire started by a FAADS missile. The missile was fired more than two hours before the crash. A P2V aircraft, Forest Service Number N96271 ["Tanker 07"], owned by Black Hills, was dispatched in response to the request for aerial fire suppression. Tanker 07 was piloted by Nathan Kolb and co-piloted by Woodard Miller, employees of Black Hills Aviation who were not Department of Defense personnel. Tanker 07 obtained authorization to enter the missile range's airspace from the missile range air controller. During the flight, Tanker 07 crashed on the missile range and both pilots were killed. The crash site was located approximately fifteen miles into the interior of the missile range, and was inside the testing site for the FAADS Project.
Probable cause:
Following the crash, an attorney from the Army Judge Advocate General's [JAG] Office at the missile range ordered markers to be placed at the crash site, and aerial photographs were taken. At that time, the Army JAG Officer anticipated litigation regarding the crash. Personnel at the missile range contacted the National Transportation Safety Board [NTSB] and the Army Safety Center in Fort Rucker, Alabama, and inquired whether either of these entities wished to investigate the crash. The NTSB replied that it was not interested in investigating, but would do so if specifically requested to do so by the missile range. Neither entity actually investigated the crash. Colonel Gary Epperson of the missile range was appointed to conduct an Army Regulation 15-6 Collateral Investigation into the facts and circumstances of the crash. The scope of the AR 15-6 investigation encompassed only the activities of the Army in regard to the crash of Tanker 07, and did not seek to determine the precise cause of the crash. Colonel Epperson's investigation consisted of viewing the crash scene, meeting with eyewitnesses to the crash, and asking for written statements.
