> "Over a two-year period, nearly 400 pilots, flight attendants and passengers reported receiving medical attention after these “fume events,” and four dozen pilots were described as impaired to the point of being unable to perform their duties, The Times found."
This same two year period flew about 280 million "passengers", obviously not unique, but 400 / 280 000 000 ~= 1 in 15000
I don't think that this is about being covered up so much as obfuscated. That's a low-frequency event.
Harm caused by occupational exposure to hazardous chemicals is usually a chronic, cumulative, delayed onset type of thing.
But actually, I typo'd quite badly: the ratio is 1 in 700000, not 1 in 15000 (how did I make that mistake?)
Anyways, I hope it's clear that a 1 in 700000 event is hard to detect.

Sorry, I don't see any death in the logs, can you point me to recent aviation deaths that were caused by this?
> or become incapacitated
For instance, you have a ~1 in 366 chance of being in a car accident per 1000 miles driven.
I think you should stay home more often, or learn more about probability.
