Two US television news helicopters collided and crashed while covering a police chase in Phoenix, Arizona yesterday, killing four people.
Both helicopters went down in a park in central Phoenix and caught fire.
The collision happened as the two choppers broadcast live coverage of police pursuing a truck. Cameras aboard both aircraft were pointed at the ground, so viewers did not witness the accident.
The first indication of trouble came when pictures from the helicopters went dead.
Television station KNXV reported that it owned one of the choppers.
The other was from KTVT, which reported that both the pilot and photographer were killed in the crash. Just before the collision, the driver of the truck that was being pursued had jumped out of pickup and hijacked another truck.
News helicopters from other television stations were also in the area.
