At least two people have been killed in a mid-air collision involving two small planes near an airport in the US state of Arizona.

One plane is said to have landed safely, while the other crashed near a runway and burst into flames.

Forbes says the FAA has classified the crash as a “general aviation” incident, which covers private planes and is different from “commercial aviation.”

The FAA adds that Marana Regional Airport – where the accident occurred – “is an uncontrolled field,” meaning it doesn’t have an air traffic control tower.

The National Transportation Safety Board is investigating the collision.

This is the latest in a string of deadly aviation incidents in the United States.
