If people want to watch the crash then it's up to them. If you don't want to watch the crash, it's clearly marked as a crash video. Flying isn't always nice, happy fun. I could just as easily start ranting and raving about gun camera footage being sick and distasteful, but no! And do you know why? Because in this free world people can choose if they do or don't want to watch things. It makes you sick, don't watch it. Simple.
Now, me, I haven't even watched it. And I don't plan on doing so anytime soon.
