This is, by far, one of the most insulting posts I have ever read here. Not too mention the fact that it expresses an irrational and illogical fear.
Well, TTD (following your logic), since people die when they fly in planes, perhaps we should stay on the ground. In fact, millions of people die every year in automobile/ship/train crashes/sinkings/wrecks. So maybe we should stop that too. IN FACT, some people die while WALKING outside... you know, animal maulings, muggings, rape, etc. So maybe we should all stay barricaded in our houses and wait until our hearts stop beating so we'll all be dead and TRULY safe from danger on this Earth.
I'm sorry, but that logic is anti-progress at best, primative at worst.
Concerning the deceased astronauts, I sincerely hope these heroes who dared to push envelope of human exploraion/abilties, are given the honor and respect they and their families deserve. Without people like these astronauts, with that fire in their heart to walk the narrow ledge between new human experience and Death, we'd still be living in the trees and worshipping that big round face in the sky we call the Moon. 🙂
