I've seen the ads. I wonder if a plane whacked one of those pylons with a prop if it would be catastrophic? At that altitude and speed, if they crash, is there any hope of survival.
At those speeds, the difference between hitting the water and the ground are neglible. Ever crash water skiing at 30mph, you get the idea, now lets go 100+.
I wonder if there are special safety designs in those planes for such eventualities.
