The Federal Aviation Administration is looking into a close call collision incident at Phoenix Airport.
A Delta flight at Phoenix Sky Harbor International Airport had been cleared to land when a collision warning was triggered in the cockpit.
Another inbound flight, United Flight 1724 from San Francisco, also got a collision warning.
Both were able to land safely ‘after experiencing a loss of required separation when they were inbound,’ the FAA said.
The agency said air traffic control ordered corrective instructions to pilots at the controls of both planes.
The planes were about 1,200 feet apart and a 875 feet difference in altitude.
