UTG 727 destruction

I've never seen anyone laugh at failure, I've only seen them heading out in frustration.
I have, especially if you sit in the bleachers. Some people laugh at the relief they didn't get hurt.
There is a saying, 'It's always funny until someone gets hurt' or 'Everything is funny as long as it is happening to somebody else'.
Like it or not, it's a normal psychological reaction. Shock, then relief.
Then again we Aussies tend not to be as tightly wound as others .
