2002 Überlingen mid-air collision - Wikipedia, the free encyclopedia

The International Civil Aviation Organization (ICAO) did not take action regarding the near-miss which occurred about a year before the Bashkirian-DHL collision. During the 2001 Japan Airlines mid-air incident, two Japanese airliners, both Japan Airlines, nearly collided with each other in Japanese skies. Disaster was avoided because one of the pilots made evasive manoeuvres based on a visual judgement, and 677 people were saved. If the collision had occurred, it would have been the deadliest civil aviation accident in terms of passenger lives. The aircraft missed each other by less than 100 metres, and the abrupt manoeuvre necessary to avert disaster left about 100 occupants hurt on one aircraft, some seriously. Japanese authorities called for measures that would prevent similar accidents from happening, but ICAO did not further investigate the incident until after the Germany collision. In addition four near misses in Europe occurred before the Germany disaster because one set of pilots obeyed the air traffic controllers while the other obeyed TCAS. The ICAO decided to fulfill Japan's request 18 months after the Japan Airlines incident.
