A sad story that I saw today;
A routine US Airways flight from Charlotte to St. Thomas in January 2010 turned into a nightmare when a toxic fume leak filled the cabin with tricresyl phosphate (TSP) — a dangerous chemical from the engines.

Seven crew members, including Captain Dave Hill and First Officer Macon “Mick” Fowler, suffered dizziness, headaches, and a strange “stinky feet” smell. Passengers had no idea, but the crew quietly fought through the flight. Fowler later said that if it had lasted 15 minutes longer, they might not have been able to land.
Doctors confirmed chemical exposure, and US Airways admitted the leak.
The aftermath was tragic: Hill lost his medical license and took his life years later; Fowler never flew again. Flight attendants Sylvia Baird and Denise Weiss still suffer lasting damage.
Now, survivors are pushing for mandatory cabin air sensors to prevent this from happening again.
