SAO PAULO, Brazil, Sept 29 (Reuters) - A passenger plane flown by Brazilian airline Gol <GOLL4.SA> disappeared over the Amazon jungle
on Friday after losing radar contact and failed to arrive at its destination with 155 people on board, the company said.
The head of Brazil's airports authority, Infraero, said the Gol aircraft collided with another smaller plane in the Amazon region
, the Globo news agency reported.
The smaller plane, an executive jet, was able to land
in a town called Serra do Cachimbo even though it suffered wing damage, Globo reported.
Gol flight 1907, which officials were trying to locate, left Manaus at 2:36 p.m. local time (1836 GMT) but did not arrive in Brasilia at 6:12 p.m. (2112 GMT) as scheduled, a spokesman for the Manaus airport said.
Celso Gick, a spokesman in the Amazon region for Infraero, said the Boeing 737-800 was carrying 149 passengers and six crew members.
Gol said the flight had 155 passengers on board but made no mention of 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.
CBN radio said at least 20 passengers were employees of Yamaha Corp. <7272.T>, the Japanese conglomerate.
"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
