Varig Flight 254 was a Boeing 737-241, c/n 21006/398, registration PP-VMK, on a scheduled passenger flight from São Paulo, Brazil, to Belém, Pará, Brazil, with several intermediate stopovers, on 3 September 1989. Prior to take off from Marabá, Pará, towards the final destination, the crew entered an incorrect heading into the flight computer. Instead of flying towards its destination, the plane flew due west and after some time was over a remote area of the Amazon jungle. Attempts to reach an alternative airport were unsuccessful, and the plane eventually ran out of fuel. The pilot made a belly landing in the jungle, 1,050 mi (1,690 km) northwest of Rio de Janeiro. There were 54 occupants on board—48 passengers and a crew of six; 13 passengers died, and many more sustained serious injuries.
