Well, now, in CA it costs about 25 cents more per 65 miles of travel
than does gasoline. That's hardly "insane". You have not identified
any safety risks that are significantly different from those
associated with gasoline.
See what a damaged oxy (i.e. non-flammable) bottle did to Qantas
QF30. I assume you've seen the news.
Yes, I have and your repeating this ad nauseum does not change the
outcome, which is that the plane landed safely.
See what a damaged gasoline tank did to numerous B-17s and B-24s and
Lancasters and whatnot during WWII. It was a lot worse than what that
oxygen bottle did.
