What to say: I was going to start by linking to the AP piece submitted shortly before the explosion, but, as usual, The Agitator beat me to it, so go there for the link, as well as some inspiring words from President Reagan when Challenger blew up. I'm sure many will try to find the terrorism angle due to the Israeli astronaut ("Hebrewnaut"??), but I would imagine, this is just one of those tragic accidents. I certainly do not wish to downplay what happened, but if one considers that our space program has really only had three fatal incidents in the past 35 years, one might suggest that that is a fairly good track record given how many things can go wrong with each launch/re-entry. Anyway, our prayers are with the families.
