The great thing is, it’s not just for flights! My travel insurance gives me coverage as long as I’m travelling outside my home. It literally covers damage to my bike if I’m visiting my parents for the weekend, or road assistance if my car breaks down on my way to a hike.
That’s essentially why I have it: Pretty much everything I bring with me on any trip that’s not to-from work is covered.
If I remember my history correctly, a major point of the gas chambers was that the prisoners were convinced that they had been sent to a labour camp, and were sent into the chambers to shower. By convincing people that they weren’t in immediate life threatening danger, it was much easier to control them.
Of course, nobody could even imagine the absolute horror of the Holocaust. If you told me that someone would take hundreds of thousands (millions) of fit, working age people and simply wipe them out, I would have a much easier time believing the other guy that said “no, you’re being sent to take a shower before being placed in a labour camp. Life will be hard, but obviously we wouldn’t waste resources just killing everyone on the spot.”
