The decision to fly was left to the pilot, who chose to take off even though a considerable amount of time had elapsed since the plane’s last de-icing. At 3:45 p.m., the Boeing 737 jet taxied to the airport’s longest runway, which was 7000 feet long.

As Air Florida Flight 90 began to speed down the runway for takeoff, it struggled to gain speed. Once the jet became airborne, it never gained the proper speed and altitude for a safe takeoff.

To complicate matters, the plane’s takeoff was to the north, which requires a hard left turn over the 14th Street bridge to follow the course of the Potomac River.

The jet flew about one mile before it stalled. At 4:01 p.m., it slammed into the top of the 14th Street Bridge, crushing and scattering several vehicles. The 737 jet plunged over the bridge and into the ice-covered Potomac River
