The Federal Aviation Administration says it is investigating an incident in which a commercial flight aborted a landing as another plane apparently was taking off from the runway the first plane intended to use this week in upstate New York.

Preliminary data from FlightRadar24 shows that the PSA flight, which was coming from Washington, and Endeavor Air 5421, which was heading to New York, were as close as 625 feet from each other vertically as their courses began to converge.
