4 passengers were killed in Arizona during a mid-air plane crash earlier in the day, each of the single engine aircrafts were carrying two passengers.
The collision occurred at around 10 a.m., over 67th Avenue and New River Road in Phoenix.
It is unclear what caused the collision, and the Federal Aviation Administration and National Transportation Safety Board are investigating, according to ABC.
Several bystanders reported seeing the planes collide but the flight directions of the planes before the crash or other details weren’t immediately available, officials said.
“Both of them collided. We don’t know how or what,” said Phoenix Fire Department Capt. Larry Nunez. “The skies are clear.”
Circumstances of the crash are under investigation, said Capt. Dave Wilson of the Daisy Mountain Fire Department.
Phoenix fire crews went to the area and found the two planes. A Cessna apparently had caught fire and was destroyed. The other craft, a Piper Archer, was mostly intact.
Authorities found four people dead.
“I thought possibly we might have survivors,” said battalion Chief Gary Bernard of the Peoria Fire Department.
According to Capt. Darren Salotti of the Daisy Mountain Fire Department, the mostly intact aircraft looked like it tried to land. Both occupants of that plane were confirmed dead. The identities of the victims have not been released.
Deer Valley Airport is one of the busiest general aviation airports in the country and has more than 1,200 planes based there.
It has a fueling station, avionics repair, aircraft rentals, new and used aircraft sales, a pilot shop, a restaurant, charter flights and two flight-training schools — one at Westwind School of Aeronautics and TransPac Aviation Academy.
The Cessna is registered to Westwind Aircraft Leasing LLC, which has an office at Deer Valley Airport. The Piper was registered to Bird Acquisition LLC, which also has an office at that airport. The address is the same as TransPac Aviation Academy.
TransPac Aviation Academy officials said Friday that they still were gathering information about the crash and declined to comment.
Federal investigators were en route to the scene of the collision, but the National Transportation Safety Board typically takes several months to determine a probable cause for air accidents, Federal Aviation Administration spokesman Ian Gregor said.
