A Delta Air Lines plane nearly collided midair with a T-38 Air Force jet near Ronald Reagan Washington National Airport (DCA) on Friday in an incident that the FAA is investigating. 

One hundred thirty-one passengers and five crew members were reportedly on board the flight to Minneapolis-St. Paul, as the four T-38 jets performed a flyover several miles from the airport at Arlington National Cemetery.

The near-collision occurred due to a "loss of separation," meaning the aircraft were closer to each other than allowed by minimum safety standards.

Notably, this comes two months after an American Airlines flight collided with a military helicopter, claiming 67 lives at DCA.
