RE: Falcon 9 v1.1
Yeah, I've been following all of the conjecture based on that one small image of it on the nasaspaceflight.com forums. The industry guys and armchair rocket builders are wondering if SpaceX has re-arranged the engine layout from a 3x3 block to an octagon with one in the middle. It's all guessing until more information becomes available.
Sojourner, are you on the nasaspaceflight.com forums? I post there quite a bit. (as Lars_J) I've expressed a lot of skepticism towards the speculation from that single image.
