Idiot. Seriously, this isnt an adrenaline thing, its just stupidity.
You don't see any usefulness in all the data that will come from this experiment? I wonder if Buzz Aldrin and Neil Armstrong were stupid too? Maybe to some, but to others, they were hero's for doing what others couldn't/wouldn't in the name of human advancement.
Sacrifices are made everyday by those who wish to test the limits of human existence. They are all useful in their own way.
