The only thing I regret about the Scaled Composites effort is that they're not using a B-29 as the drop ship. (I still get chills watching the B-29 takeoff at the beginning of The Right Stuff; the music and imagery bring to mind something akin to being in a cathedral.) Now there's a movie that should be adapted to the IMAX screens. I concur, the B-29 is one magnificent bit of engineering. I doubt the CAF would want to carve up FiFi's underbelly for drop-ship duty, though. I watched that B-29 fly out of the Baton Rouge airport one Fall afternoon - the movie does it justice, but just barely.

Rutan is making me jealous.
I'd give anything to be sitting at the tarmac watching as they do the next run.
