How does a wet cloth really help (scientifically) to survive an airplane crash?

As others have said, they focused on the main cause of deaths in fires
and that is the gases. That doesn't mean that particles are not also
dangerous and life threatening.
Nothing I found, so far, says that the particles are life
threatening.
The HCN gas can kill you in a couple of minutes, for example.
There was one reference which did say the wet cloth trapped particulate
matter:
http://wenku.baidu.com/view/8abb4621...fcc220e6f.html
So, we can safetly assume that a wet cloth does trap particles,
but, nobody has reported any real evidence that "smoke inhalation"
(presumably that means particulate inhalation) is either immediately
dangerous, or the *reason* for the wet cloth.
News reports of people who died from smoke inhalation, incuding
Ambassador Stevens, certainly count as real evidence.
I reed and hear such reports frequently but I'm not going to take the
time to find any now. If you want to read some, search the web. There
are plenty.
Based on the evidence repoted to date, the reason for the wet rag
seems to be to trap water soluble gases, of which HCN is the most
dangerous in a cabin fire (according to all the references).
Why do you worry only about the most dangerous gas? If 3 people mug
you, and one has a .45 caliber gun, another a rifle, and the third a
Derringer, with two small bullets, and you can stop the guy with the
rifle from shooting you, will you happily let the other two guys shoot
you?
That's a pretty good analogy.
