The Transports Aériens Intercontinentaux Douglas DC-6B scheduled flight from Saigon, Vietnam to Paris, France crashed on 20 February 1956 before its third stopover 25 km North-East of Cairo International Airport due to crew error and possible fatigue.

[1][3][2][4] The crash was caused by a failing altimeter in combination with a pilot who was taking his flight exam while landing with self created limited visibility.

[7] A Transports Aériens Intercontinentaux Douglas DC-6B with tail number “F-BGOD” departed from Saigon with a delay of around 20 hours.

[2][9] A bit later, just before 3am at around 25 km North-East of the airport, the aircraft crashed in the desert on hill, broke up and caught fire.

[3] The six crew members who survived the crash consisted of: the experienced pilot in charge Charles Billot, who was injured, the inexperienced co-pilot who was still taking his flight exam Robert Rolland, two mechanics and two radio operators.

[3] In 1964, Billet stated before the magistrate in Versailles that he was conducting a part of the flight exam with the co-pilot Robert Rolland during the landing phase.

[6] Pilot Billet was blamed that he failed to monitor the co-pilot Rolland during the approach procedure and was convicted of involuntary manslaughter.
