Mojave Explosion and Tribute to Those Lost

I've been away on vacation for a few days, so I'm late with the news of the explosion and losses at Scaled Composites. The tribute posted on Transterrestrial Musings seems to me to be the most fitting expression at this point. I just read this version of the Navy Hymn in the Heinlein Reader's Companion, probably the same day the accident happened, which may be why it seems so appropriate to me.

There's more at Cosmic Log (including the comments) and many other sites.
