The Brazilian passenger plane which crashed with 155 people onboard was likely to have plunged into the ground nose first, and there was no immediate word about the fate of 155 passengers and crew members, the airport authority and Brazilian airline GOL said on Saturday (Sep 30).

According to Jose Carlos Pereira, president of the airport authority Infraero, rescue planes found a concentrated wreckage site in the Amazon jungle, indicating that the plane hit the ground in a vertical position, which means that there was little chance of survival for any people onboard.

"An accident occurred with Flight 1907," the airline said, adding that "so far, there is no confirmation of survivors."

The wreckage of the plane was found 30 km north of the Peixote Azevedo municipality, a remote area of Mato Grosso state with "difficult access," Brazil's Globo TV reported.

Rescue helicopters and military troops were trying to reach the densely forested crash site, and it remained unknown whether there are any survivors, Pereira said.

The Boeing-737 plane disappeared from the radar screen after colliding with an executive jet in the Amazon region.

The small plane managed to land with a damaged wing.

The Gol flight 1907 left the northern Manaus city in the afternoon but did not arrive in Brasilia as scheduled, Globo reported.
