January 13, 1982, was a mess. Washington D.C. was basically paralyzed by a brutal snowstorm that wouldn't quit. National Airport—now Reagan National—was struggling to stay open. People were tired, cold, and desperate to get home. Among them were the passengers of Air Florida Flight 90, a Boeing 737-222 headed for Fort Lauderdale. They never made it. Instead, they became part of the most famous plane crash in the Potomac, a disaster that fundamentally changed how we fly in winter.
It wasn't just a mechanical failure. It was a perfect storm of human error, bad timing, and a freezing river.
The plane sat on the tarmac for way too long. De-icing had been done, but the snow kept falling. In a move that still makes pilots cringe today, the crew tried to use the reverse thrust of the engines to back out of the gate because the tug was stuck. That’s a huge no-no in those conditions. It sucked up slush and ice, blowing it right back onto the wings. By the time they finally got to the runway, the plane was heavy, cold, and dangerous.
The 30 Seconds That Changed Everything
When the pilots finally pushed the throttles forward for takeoff, something was wrong. The instruments told them they had plenty of power. But the instruments were lying. Because of ice buildup on the engine probes, the cockpit showed a high EPR (Engine Pressure Ratio) that wasn't actually there. They were trying to take off with much less thrust than they needed.
"It’s a losing battle," the co-pilot, Roger Pettit, actually said as the plane struggled to gain speed. He noticed the gauges looked weird. He mentioned it. But the captain, Larry Wheaton, stayed the course.
The plane barely got off the ground. It cleared the end of the runway but couldn't climb. It shook violently. At 4:01 PM, the Boeing 737 slammed into the 14th Street Bridge. It crushed several cars, killed seven people on the bridge, and then plunged into the ice-choked Potomac River.

It sank fast.
Most of the 79 people on board died instantly or drowned. But six people surfaced in the freezing water, clinging to the tail section—the only part of the plane left floating. This is where the story turns from a technical failure into a legendary display of human grit.
Heroes in the Ice
You've probably heard of the "Man in the Water." His name was Arland D. Williams Jr.
As a Park Service helicopter arrived to pull people out, Williams did something unthinkable. Every time the rescue rope was lowered to him, he passed it to someone else. He was the most exhausted, the most injured, but he kept handing off his chance at life. When the helicopter came back for him for the final time, he was gone. He’d slipped under the ice.
Then there was Lenny Skutnik. He was just a bystander, a government employee watching from the shore. He saw a woman, Priscilla Tirado, losing her grip on the rescue line. She was too weak to hold on. While everyone else watched in horror, Skutnik stripped off his coat and dived into the literal ice-water. He swam out, grabbed her, and dragged her to the bank.

It was raw. It was unscripted. It was the kind of thing that makes you realize how thin the line is between a normal Tuesday and a national tragedy.
Why the De-Icing Failed
The technical side of the plane crash in the Potomac is a masterclass in what happens when you get complacent. The crew hadn't turned on the engine anti-ice system. If they had, those probes wouldn't have iced up, and they would have seen the real power levels.
- Reverse Thrust Blunder: Using reverse thrust at the gate pushed wet snow into the engine components.
- The Lead-Follow Effect: They were following a DC-9 too closely on the taxiway, thinking the heat from its engines would melt their ice. It actually did the opposite—it melted the snow into slush, which then refroze into a solid sheet of ice on the 737's wings.
- Pitch Issues: Ice on the leading edge of a wing doesn't just add weight; it ruins the shape of the wing, destroying lift. The plane stalled almost the second it left the tarmac.
The Legacy of Flight 90
If you fly today in a snowstorm, you’ll notice the pilots are obsessive about de-icing. You might sit at the gate for an hour, then go to a "de-ice pad" right before takeoff. You can thank the plane crash in the Potomac for that. Before 1982, the rules were a bit more "discretionary." Now, they are ironclad.
This crash also revolutionized Crew Resource Management (CRM). In the 80s, the Captain's word was law. If the co-pilot saw something wrong, he often didn't feel empowered to demand a stop. After Flight 90, the industry realized that hierarchy can be deadly. Pilots are now trained specifically to listen to their subordinates, and co-pilots are trained to be assertive when they see a red flag.
The 14th Street Bridge was renamed the Arland D. Williams Jr. Memorial Bridge. It’s a constant reminder for commuters driving into D.C. that heroes exist in the most mundane places.

What We Learned About Survival
Survival in water that cold is measured in minutes, not hours. The victims didn't just have to survive the impact; they had to fight hypothermia that shuts down the muscles almost instantly.
One of the biggest takeaways for search and rescue was the need for better equipment. The Park Service helicopter, "Eagle 1," wasn't really a rescue bird, but pilots Gene Windsor and David Collier pushed it to the absolute limit. They hovered so low that the skids were practically in the water. Today, rescue protocols for urban waterways are much more sophisticated, with specialized gear ready at a moment's notice.
Honestly, the whole thing feels like a movie, but the reality was much grimmer. The recovery divers had to work in pitch-black, freezing water, feeling their way through jagged metal to recover bodies. It was traumatizing work.
Misconceptions About the Crash
People often think the engines failed. They didn't. They were running just fine—they just weren't being pushed hard enough because the pilots thought they were already at max power.
Another myth is that the airport should have been closed. Maybe. But aviation relies on the "Pilot in Command" to make the final call on safety. The system is built on the idea that the person in the cockpit knows their aircraft's limits. On that day, the system broke.
Moving Forward: Safety First
If you're a frequent flyer, don't let this story scare you. Instead, let it reassure you. The lessons from the plane crash in the Potomac are literally written into the flight manuals of every commercial jet in the sky. We don't make these mistakes anymore because we paid such a high price to learn from them.
Next Steps for the Curious:
- Research the NTSB Accident Report AAR-82-08. It’s the official breakdown and is surprisingly readable if you want the technical "why."
- If you're ever in D.C., visit the Arland D. Williams Jr. Memorial Bridge. It puts the scale of the event into perspective when you see how short the distance was between the runway and the water.
- Look into Crew Resource Management (CRM). It’s a fascinating field of psychology that started in cockpits but is now used in operating rooms and fire stations to save lives.
- Check your own "get-there-itis." The pilots of Flight 90 were in a hurry. Sometimes, the bravest thing you can do in a high-pressure situation is to say, "No, we aren't ready yet."
