Even with these odds I'd gladly hop on a shuttle tomorrow - even before they conclusively find the cause of the Columbia accident.
120 people will die today in auto accidents in the US. Should we give up on the automobile? No, it's an acceptable risk for the benefit it gives. The same goes for space exploration.
Me also.. In a second.
Man was made to explore and nothing is "conquered" till there's an American standing on it.
Everyone is going to die.. It's a fact. Its just a matter of when.
They died with glory and honor, knew the risks and didn't care.
There's no reason to abandon the space program over our fallen heroes.
