A midair collision involving two small planes in southern Arizona killed at least two people Wednesday morning, authorities said.

Federal air-safety investigators said two people were aboard each plane when they collided near Marana Regional Airport on the outskirts of Tucson.

One plane landed uneventfully and the other hit the ground near a runway and caught fire, the National Transportation Safety Board said, based on preliminary information before its investigators had arrived.

Last week in Arizona, one of two pilots died on a private jet owned by Motley Crue singer Vince Neil after the aircraft veered off a runway in Scottsdale and hit a business jet.
