On January 29, 2025, a regional jet operated by American Airlines (specifically, a Bombardier CRJ‑700 flown for its subsidiary PSA Airlines) was on final approach to Ronald Reagan Washington National Airport (DCA) near Washington, D.C., when it collided mid‑air with a U.S. Army Black Hawk helicopter over the Potomac River. 
Both aircraft plunged into the river; there were no survivors among the 67 people onboard (64 on the jet [60 passengers + 4 crew] and 3 on the helicopter). 
The accident is the deadliest aviation disaster in the United States since 2001 and the worst in many years.

Investigators are examining key factors such as the altitude of the aircraft at the moment of collision, the flight paths and separation protocols, communications with air traffic control, and helicopter routing near a busy commercial airport. For example, data show the jet was at about 300–400 feet when the collision occurred, and the helicopter may have been above its authorized altitude. 
In the wake of the crash, the Federal Aviation Administration (FAA) restricted helicopter traffic around the airport and air‑space operations have come under renewed scrutiny.
