Toxic Fumes Are Leaking into Airplanes, Sickening Crews and Passengers

A lot of people think planes are this sealed tube in the air. Nope, they use compressor stages of the engines to pressurize the cabins. This kind of thing can happen. They should have been able to close off the effected engine from pressurizing the cabin and the other should have been able to clear the air quickly, unless the was another failure too.

I've been on some where you can smell the jet fuel (kerosene) when they start the engine because they forgot to close off the cabin. They said it was normal and "harmless". It was probably harmless for me, considering the infrequent flights I take, but not to cabin crew.

I refuse to fly. 75% of the time I've flown, I've smelled the diesel fuel-like odor of Jet A in the cabin at startup. It's way too normalized.

Also, like astronauts, flight crew receive significant cumulative ionizing radiation exposure.

Airbus A350, Airbus A220(ex Bombardier C-Series), Boeing 787, Embraer E-Jet E2 Series, don't use it. Maybe future models of ATR-72(or descendants) won't.
