What is the alternative, curl up and cry? Doing anything (especially anything interesting) involves taking risks. Not to mention that I probably have more chances of being arrested or conscripted then actually suffering in an airplane accident, they are still quite safe. I don't think that worrying about everything, especially things as basic as an airplane travel, will do you any good.

One of the surprising things I've learned in this online world of ours is that some people simply worry about everything. I don't get it either.
