Circumstances:
Following an uneventful flight from Bombay, the crew started the descent to Bangkok-Don Mueang Airport by night. On approach, the pilot reported runway in sight and was cleared to land on runway 21L.

The aircraft and several buildings were killed. All 53 occupants on board the B707 were killed as well as 20 people working in the factory. At the time of the accident, the visibility was estimated to be 4 km.
Probable cause:
The accident was the consequence of several errors on part of the flying crew who continued the approach below the minimum safe altitude until impact with ground.
