I came across this video tonight of various machines in precarious positions and rescue attempts. It never ceases to amaze me how many people can't think through what they're actions might result in. https://youtu.be/d_72_4qaJYA
Too funny.
What never ceases to amaze me in those videos and in real life is how many people just stand there and watch things crash down 5' in front of them. If I'm not running the machine I run at the first sign of danger, I can always walk back.
