US investigators have located key parts that might help reveal the pilot’s efforts to save a plane that crashed into a house, killing all 49 people on board and one person on the ground.

A commuter plane that smashed into a house apparently plunged flat to the ground rather than nose-diving, ending up pointed away from the airport it was trying to reach, US investigators said.

INVESTIGATORS picked through the charred wreckage of two news helicopters that collided and plummeted to the ground while covering a police chase, the debris scattered about 100 yards in all directions.
