Two people were confirmed dead after “two small planes collided mid-air at Marana Regional Airport in Arizona around 8:30 a.m. local time.” The crash involved a Cessna 172S and a Lancair 360 MK II, with two people on each plane.

One aircraft “managed to land,” while the other “caught fire after crashing near the runway.” The National Transportation Safety Board (NTSB) confirmed that “the fatalities came from one aircraft,” while the other two occupants were unharmed.

The airport “lacks an air traffic control tower” and is “temporarily closed for investigation.”

Marana officials expressed their “condolences and thanked responders for their swift action.”

The airport is part of the FAA’s Air Traffic Control Tower Program, which could lead to “future improvements.”
