Brazilian military officials say they have recovered the flight data and voice recorders from the wreckage of a Boeing 737 passenger jet that crashed in the Amazon jungle Friday.
Search teams found the two devices Monday in a remote rainforest in northern Brazil, as they continued looking for the bodies of the victims. All 155 people aboard the plane were killed but, so far, only a handful of bodies have been located at the crash site, near Peixoto de Azevedo in Mato Grosso state.
Officials believe the Brazilian GOL passenger plane crashed after colliding in mid-air with a Legacy executive jet. The smaller plane managed to land safely at a nearby air force base. Its seven passengers and crew were unhurt.
Authorities hope the recorders will explain how the two planes, both equipped with the latest anti-collision technology, collided in mid-air.
Brazil is observing a third day of national mourning Tuesday, for the victims of the disaster - the deadliest in the country's history.
