It's also so if a window fails you don't get sucked all the way out (although you can still be killed if you're sucked partially out, as happened on a Southwest Airlines flight to an unfortunate passenger.)
Cattling statistics like this is silly.
If you showed fat people images of obesity and said that they'd be healthier if they lost their weight, you would also cattle the statistics and look at how many fat people decided to suicide versus how many took the advice (or didn't)? What a dumb way to construct advice.
