Gol Transportes Aéreos Flight 1907 was a Boeing 737-800 SFP, registration PR-GTD, on a scheduled passenger flight from Manaus, Brazil, to Rio de Janeiro, which collided in mid-air with an Embraer Legacy business jet on September 29, 2006 over the Brazilian state of Mato Grosso. All 154 passengers and crew aboard the Boeing 737 were killed as the aircraft crashed into an area of dense rainforest, while the slightly damaged Embraer Legacy landed safely with its seven occupants uninjured.
The accident was the deadliest in Brazil's aviation history at the time, surpassing VASP Flight 168, which crashed in 1982 with 137 fatalities near Fortaleza. It was subsequently surpassed by TAM Airlines Flight 3054, which crashed on July 17, 2007 with more than 190 fatalities. This accident also triggered a major crisis in Brazilian civil aviation.
