January 13, 1982, was a miserable day in Washington, D.C. It wasn’t just cold; it was that bone-chilling, wet freezing that shuts down a city. National Airport—now Reagan National—was struggling. For nearly two hours, it closed entirely because of a snowstorm that just wouldn't quit. When it finally reopened, the Flight 90 disaster on the Potomac was less than an hour away from becoming a grim piece of American history.
Snow piled up on the wings of the Boeing 737. It looked like a powdered donut. Captain Larry Wheaton and First Officer Roger Pettit were sitting in the cockpit of Air Florida Flight 90, waiting for their turn to get out of the slush. They were frustrated. They were behind schedule. And honestly, they made a series of small, human mistakes that added up to a catastrophe.
The plane crashed into the 14th Street Bridge just 30 seconds after liftoff. It crushed seven vehicles on the bridge and plunged into the ice-choked river. Out of 79 people on board, only five survived. It’s a story of technical failure, sure, but it’s mostly a story about human psychology, bad decisions in the cold, and a hero who didn't even have a name for days.
The Deadly Decision to Use Reverse Thrust
Here is the thing about ice: you can’t just wish it away. While waiting to taxi, the pilots were worried about the buildup on their wings. They’d already been de-iced once, but the delay was so long that the fluid was losing its edge. Instead of going back for another spray—which would have cost more time—they tried something clever. Or what they thought was clever.
They used the "reverse thrust" of the engines to try and back away from the gate.
Bad move. Basically, that sucked up a mixture of slush, ice, and freezing water and blew it right onto the leading edges of the wings and into the engine sensors. It was a recipe for a stall. They didn't know it yet, but their instruments were about to lie to them.
When they finally got to the runway, the pilots noticed the engine gauges looked weird. Pettit actually mentioned it. He said, "That doesn't seem right, does it?" He was looking at the Pressure Ratio (EPR) gauges, which told them how much power the engines were putting out. Because the sensors were blocked by ice, the gauges showed they had plenty of thrust.

In reality? They were barely moving.
Wheaton told him it was fine. He thought the gauges were just acting up because of the cold. They decided to go for it. As the plane lumbered down the runway, it took much longer to reach takeoff speed than it should have. They weren't accelerating fast enough. But the "official" numbers on the dash said they were good to go.
30 Seconds of Terror and the 14th Street Bridge
The takeoff was sluggish. The plane barely climbed. Almost immediately, the "stick shaker"—a device that vibrates the control yoke to warn pilots the plane is about to fall out of the sky—started rattling.
"Forward, forward," Wheaton said, trying to get the nose down to gain speed. But it was too late. The wings were so contaminated with ice that they couldn't produce lift. The Boeing 737 stayed in the air for less than a mile.
It cleared the end of the runway, but it couldn't clear the traffic.
Drivers on the 14th Street Bridge looked up to see a massive jet screaming toward them. It clipped the bridge, tearing the roofs off cars and killing four people on the ground instantly. Then, it nose-dived into the Potomac River. The ice on the river was thick, but not thick enough to hold a 737. The plane broke apart and sank into the 44-degree water.

Most of the passengers died on impact or drowned as the fuselage sank. Only the tail section stayed afloat for a few minutes. Six people managed to scramble out of the wreckage and cling to the tail, bobbing in the freezing water surrounded by jet fuel and jagged ice.
The Man in the Water: An Unparalleled Act of Sacrifice
The rescue was a mess at first. D.C. was paralyzed by the snowstorm. Ambulances couldn't get through the gridlock. The only way to get to the survivors was by air. This is where the story of the Flight 90 disaster on the Potomac turns from a tragedy into a legend of human bravery.
A U.S. Park Police helicopter, Eagle 1, piloted by Donald Usher and Gene Windsor, arrived on the scene. They hovered just feet above the ice, risking their lives as the rotors kicked up a blinding spray of freezing water. They dropped life rings to the survivors.
One man, later identified as Arland D. Williams Jr., did something incredible. Every time the helicopter dropped a line to him, he passed it to someone else.
He did it once. Then twice. He helped Kelly Duncan, the only crew member to survive. He helped Joe Stiley and Patricia Felch. He kept giving away his chance at life. When the helicopter finally came back for him, the tail section had shifted and sunk. He was gone.
He was the only person to die from drowning that day; everyone else died from the impact. They later renamed the bridge the Arland D. Williams Jr. Memorial Bridge. It’s a fitting tribute to a guy who, in the middle of a literal nightmare, decided that five other people were more important than he was.

Why This Crash Changed Everything for You
If you’ve ever sat on a plane for two hours while trucks spray orange or green goo on the wings, you can thank (or blame) Air Florida 90. Before 1982, de-icing was sort of a "best effort" thing. After this, the FAA got strict.
- De-icing Fluid Standards: They realized that the fluid they were using didn't last long enough. This led to the development of Type II and Type IV fluids, which "stick" to the wing even during taxiing.
- Sensor Heating: The crash proved that engine sensors needed better heating elements to prevent the kind of false readings that fooled Wheaton and Pettit.
- CRM (Crew Resource Management): This is a big one. The co-pilot, Pettit, knew something was wrong. He spoke up. But because of the "captain is king" culture of the time, he didn't push hard enough, and the captain brushed him off. Today, pilots are trained specifically to challenge each other. If a co-pilot says "this looks wrong," the captain is trained to listen, not ignore.
Practical Insights from a Dark Day in Aviation
The Flight 90 disaster on the Potomac wasn't caused by a mechanical "break" in the sense of a bolt snapping. It was a failure of protocol and a misunderstanding of how cold weather affects aerodynamics.
For those who travel today, there are a few things to keep in mind that come directly from the lessons learned here:
- Trust the De-icing Process: If your pilot says they need to go back for a second de-ice, don't groan. The "holdover time" for de-icing fluid is a hard limit. If they miss that window, the wing becomes a giant, heavy paperweight.
- The "Clean Aircraft" Concept: This crash established the rule that a pilot must have a visual confirmation that the wings are clean before takeoff. No exceptions.
- Communication is Safety: Modern aviation safety relies on the "flat" hierarchy in the cockpit. This approach has migrated to other industries, like surgery and nuclear power, where the junior person is encouraged to "stop the line" if they see a safety risk.
The legacy of Flight 90 is written in the safety manuals of every airline operating today. We fly safer because of the mistakes made on that snowy Wednesday in D.C., and because of the incredible bravery of the rescuers and a man who refused to save himself until everyone else was safe.
If you're interested in the technical side of this, you can look up the NTSB report AAR-82-08. It's dry, but it's a masterclass in how small errors cascade into a disaster. It’s also worth visiting the memorial near the bridge if you’re ever in D.C. during the winter—it puts the scale of the event into a very different perspective when you see how wide that river really is.
To understand more about modern flight safety, research the "sterile cockpit rule" which was further refined after this era to ensure pilots stay focused during critical phases of flight. You can also look into the history of the U.S. Park Police aviation unit, which still operates today and uses the lessons from the Potomac rescue in their training.
