Federal authorities are investigating after a "close call" was reported Tuesday night at Newark Liberty International Airport in New Jersey, involving a commercial jet and cargo aircraft.

National Transportation Safety Board (NTSB) officials confirmed the "close call" happened when an Alaska Airlines Boeing 737 overflew a FedEx Boeing 777 while both jets were attempting to land on crossing runways.

The Federal Aviation Administration (FAA) said that at about 8:15 p.m. local time, an air traffic controller instructed Alaska Airlines Flight 294 to perform a "go-around" because FedEx Flight 721 was cleared for the final approach to an intersecting runway.

A FedEx spokesperson told Fox News Digital that "following instructions from air traffic control, the flight crew of FedEx flight 721 landed safely without incident at Newark Liberty International Airport."

The incident came just a year after an Army Black Hawk helicopter collided midair with an American Airlines passenger plane near Ronald Reagan Washington International Airport, killing 64 people on the American Eagle flight and three aboard the military helicopter.

Newark Liberty International Airport is one of the busiest airports in the U.S., serving tens of millions of passengers annually. As of late, the airport has been plagued by air traffic controller shortages, leading to strained operations and major delays. 

FAA and NTSB officials are investigating the incident.
