Aviation in general, along with the government doesn’t point out risks to aviation because in the past the idea was to promote aviation. Government encourages flying, using statistics to justify that argument. If passengers were to have to sign a waiver like skydivers do so that the risks are plainly pointed out in writing, aviation in general would probably be mostly military with very little civilian airplanes flying. Especially with the risk averse society we have today, not to mention the greedy tort lawyers who would pounce on any crash.
