Two people are dead after a car flew off the Arlington Memorial Bridge and into the Potomac River when it collided with another car on Thursday evening.

A dramatic plane crash in frigid temperatures. And a search and rescue that saved lives on the same partially frozen Potomac River. Almost 43 years ago to the day, tragedy struck when a commercial jet − Air Florida Flight 90 − plunged into icy waters shortly after an afternoon takeoff from the same airport where a passenger jet with 64 people aboard collided with an Army Black Hawk helicopter on Wednesday night.
