A midair collision involving two small planes in southern Arizona killed two people Wednesday morning, authorities said. Federal air-safety investigators said each plane had two people aboard when they collided at Marana Regional Airport on the outskirts of Tucson.

It marks the second fatal incident at an Arizona airport in the past 10 days. On Feb. 10, the pilot of a private jet owned by Mötley Crüe singer Vince Neil was killed after a runway collision between two aircraft at Scottsdale Airport.
