[00:00:00] Speaker 1: In 1982, a routine flight turned into a national tragedy. Air Florida Flight 90 struggled to take off during a heavy snowstorm in Washington, D.C. and then it crashed moments later.

[00:00:14] Speaker 2: Recovery crews worked in the subzero waters of the Potomac River today trying to recover the bodies of victims who died in that Air Florida crash.

[00:00:23] Speaker 1: The tragedy exposed a critical weakness in winter operations. In the years that followed, the FAA moved to standardize de-icing and anti-icing procedures across the industry. Today, that responsibility falls to a specialized crew of de-icers. They brave the cold to make winter travel possible. At Chicago O'Hare alone, teams can de-ice more than 300 planes a day, most of them right at the gate.

[00:00:49] Speaker 3: It's a delicate balance and controlled chaos.

[00:00:52] Speaker 1: Planes can accumulate thick layers of ice overnight, which can reduce lift-on take-off and increase drag. This can also harm the plane's engines.

[00:01:00] Speaker 4: I just noticed, here, they'll have to get this de-iced. Oh, love it. See that? They will take that off. That's just some rime ice. I just noticed that. It should take only a second to get in there.

[00:01:12] Speaker 1: This orange liquid is a glycol mixture called type 1 de-icing fluid. It's a hot liquid that melts snow and ice off the plane.

[00:01:20] Speaker 5: When it's snowing, the whole airplane gets type 1 to get the snow off, and then type 4 to keep the snow off.

[00:01:26] Speaker 1: Type 4 is a green solution to prevent additional snow from accumulating. Once it's applied, the clock starts ticking before the plane must take off.

[00:01:34] Speaker 6: If it's really cold, the ice might be really stubborn. It might take a long time to get the ice off. So it all depends on the conditions.

[00:01:41] Speaker 3: I think I've de-iced one airplane upwards of six or seven times. The same airplane, the same flight, just because of the way the conditions were.

[00:01:49] Speaker 1: If you're delayed this winter, know that crews are working hard to get you safely to your destination.

[00:01:55] Speaker 3: If we don't properly treat the aircraft during winter operations, bad things can happen.

Summary

The transcript recounts the 1982 Air Florida Flight 90 crash during a Washington, D.C. snowstorm and how it exposed weaknesses in winter flight operations. In response, the FAA standardized de-icing and anti-icing procedures, carried out today by specialized de-icing crews who can treat hundreds of aircraft daily at major hubs like Chicago O’Hare. It explains how ice buildup reduces lift, increases drag, and can affect engines, and describes the use of hot Type 1 glycol fluid to remove snow/ice and green Type 4 fluid to prevent re-accumulation. The piece notes that conditions can require repeated de-icing and emphasizes that delays often reflect safety-critical work to prevent accidents.
