EgyptAir Flight 864

The aircraft was a Boeing 707-366C with the serial number 20763 and serial 871, that had its maiden flight on 25 August 1973. The aircraft was registered as SU-AXA and was delivered to EgyptAir, and entered service on 20 September the same year.[2] The aircraft was powered by Pratt & Whitney JT3D-7 turbofan engines.[1]

Flight 864 was a regularly scheduled international passenger flight from Rome to Tokyo with stopovers in Cairo, Bombay and Bangkok.[3] With 9 crew members and 44 passengers on board, flight 864 approached Bangkok. At 20:30 GMT (03:30 local time), the crew contacted the approach controller and reported about the distance of 33 nautical miles (61 km) from the airport’s radio beacon. At this time, conditions were reported as calm, with cloudiness from 2/8 to 4/8 at the lower border of 300 meters, air temperature of 25 °C at a dew point of 24°C, visibility of 4000 meters, and an airfield pressure of 1007 mB. Having received the radar vector to the “BK” DPRM, the crew began their approach to runway 21L. The crew reported their observations. The controller cleared the flight to land, and the crew acknowledged the transmission. Then at about 03:45, the aircraft crashed into a weaving mill building in an industrial area of the city, located 2 kilometers northeast of the end of runway 21L. The aircraft exploded on impact, and all 52 people on board were killed.[4] The weaving mill was also destroyed, with 19 people killed on the ground. The total number of victims was 71 people. At that time, the crash was the deadliest aviation disaster to occur in Thailand (it is now the sixth).[1]

Pilot error was determined to be the cause of the crash.[5] EgyptAir claimed that the Bangkok control tower had provided inadequate weather information to the crew of Flight 864.[6] The crew had also reduced the aircraft's vertical speed and did not monitor its height properly.[5][7]
