The operator of the Boeing 737, Brazilian airline Gol, has confirmed that they have lost radar contact with the plane and it has failed to arrive at its destination.
Gol flight 1907, which officials are trying to locate, left Manaus at 2.36pm local time but did not arrive in the capital Brasilia at 6.12pm as scheduled, a spokesman for the Manaus airport said.
Celso Gick, a spokesman in the Amazon region for Infraero, Brazil’s airport authority, said the Boeing 737-800 was carrying 149 passengers and six crew members.
Brazil's civil aviation authority said the plane was transporting 155 people and lost contact around the town of Sao Felix do Araguaia.
“The Air Force is in the area of the collision," Infraero President Jose Carlos Pereira, said on radio. Five air force planes were searching for the missing Gol jet.
CBN radio said at least 20 passengers were employees of Yamaha Corp, the Japanese conglomerate.
The smaller plane, an executive jet, was able to land in a town called Serra do Cachimbo even though it suffered wing damage, local media, Globo reported.
