A former top U.S. transportation safety official raised concerns after video captured two planes seemingly on a collision course near an upstate New York airport.

An American Eagle flight, which had been cleared to land at Syracuse Hancock International Airport, was caught on a police officer’s dashcam as a Delta Connections flight that had just taken off from the same runway seems to cross its paths just before noon on Monday.

The planes were about 725 feet apart at one point, CBS News reported, and experts said preliminary evidence shows the flights were not on a collision course.

Still, Robert Sumwalt, an aviation safety analyst and former chair of the U.S. National Transportation Safety Board, pointed the finger at possible air traffic control issues during an appearance Wednesday on CBS News.

“That’s not a good situation,” Sumwalt said. “Airplanes should be spaced a certain interval apart, they lost that.

“Sounds to me like this was an air traffic control issue and these things aren’t supposed to happen.”

The U.S. Federal Aviation Administration said it is investigating the incident.

Audio of the control tower’s communication with pilots on both flights showed that American Eagle Flight 5511 was given permission to land on the airport’s runway 28 despite giving Delta Connection 5421 the green light to take off from the same runway, CBS News reported.

“Wait, who’s cleared to take off on 28?” one of the American Eagle pilots says.

The American Eagle pilots were then told to abort their landing, CBS News reported, and “go around,” but the flight continued over the runway where the Delta plane was taking off before turning and descending slightly. At that point, the planes were about a mile apart.

Delta said there were 76 passengers and four crew members aboard Flight 5421, which was headed to New York City, CBS News reported. American Airlines, which operates American Eagle, said Flight 5511 was carrying 75 passengers and four crew members from Washington, D.C.

No one was injured.

“Endeavor Air (a regional branch of Delta) and Delta will work with aviation authorities as we always do in our shared commitment to safety above all else,” Delta said in a statement to CBS News.

American Airlines declined to comment, citing the FAA probe, CBS News said.
