January 13th, 1982:
Air Florida Flight 90 crashed shortly after takeoff from National Airport in Washington, DC, as a snowstorm gripped the nation's capital. The 737 lost power due to ice build-up on the wings and crashed into the 14th Street Bridge, crushing 7 occupied vehicles. The crash destroyed 97 feet of guard rail before it plunged into the icy Potomac River. 74 passengers perished, along with 4 people on the ground. Only five of the seventy-nine people aboard survived.
