Gol Airlines / Private Flight 1907Friday September 29, 2006
The flight disappeared from radar at 16:50 after leaving Manaus at 15:35, scheduled to arrive at Brasilia at 18:12. While en route the jetliner collided with an Embraer EMB-135BJ Legaacy 600 business jet. The Embraer was able to land safely at Serra de Cachimbo with a damaged wing and tail. Five passengers and two crew members on the Embraer were not injured. All 154 on board the 737 were killed. The flight recorder transcript from the executive jet showed that the pilots were told by Brazilian air traffic control to fly at the same altitude as the Boeing 737 before the planes collided. A Brazilian Air Force investigation concluded that a switched-off transponder on the EMB-135 contributed the plane crash. The report also said flight controllers failed to alert the pilots they were on a collision course and failed to notice the transponder was turned off.
