Air Crash Investigation - Mayday

On 13 January 1982, Air Florida Flight 90 takes off from a snowy runway in Washington D.C, stalls at 300 feet altitude, strikes a road bridge and crashes into the Potomac River, killing a total of 78 people. The causes were ice on the wings and the pilots' failure to turn on the engines' anti-freeze system, causing erroneous engine instrument readings.
