2025 Potomac River mid-air collision
On January 29, 2025, American Airlines Flight 5342 and a United States Army Black Hawk helicopter collided in mid-air over the Potomac River in Washington, D.C. The collision occurred at 8:47 p.m. at an altitude of about 300 feet (100 m) and about one-half mile (800 m) short of the threshold of a runway at Ronald Reagan Washington National Airport. All 67 people aboard both aircraft were killed in the crash, including 64 passengers and crew on the airliner and the three crew of the helicopter.
DCA is a call sign for Reagan airport. I had to fucking google that!
