An airplane went down in the Potomac River near Ronald Reagan Washington National Airport on Wednesday, prompting a multi-agency search-and-rescue operation, according to officials.

The Federal Aviation Administration said preliminary information indicates a PSA Airlines Bombardier CRJ700 regional jet collided in midair with a Sikorsky H-60 helicopter while on approach to the airport around 9 p.m. local time. The plane departed from Wichita, Kansas.
