This is a terrible tragedy, but alas this is the cost of progress.
I like AmiNTT have always been a bit of a space buff from when I was very little and agree these guys (and gals) are heroes.
Everyone sufferers risks of one kind or another every day, on the other hand Astronauts put themselves in much, much greater danger for the betterment of Human civilisation. They have my utmost respect.
I'm very glad that President Bush said that despite this progress will continue.

Maybe if the budget didn't get cut year after year, we'd be working with something better than 1970s technology to go to and from orbit.
They use old technology on purpose, firstly everything has to be qualified for space (radiation resistance etc.) and they only use things which are tried and tested. Using the latest tech would be a very risky move. Consequently you'll probably still find things like 68000 CPUs in the Shuttle.
NASA take a tiny fraction of the US budget, perhaps this may actually get them more.
