Update: Brief update from Sideswip on today's filming:
...from someone who works at KSC "They were filming on the pad surface all day, so they were probably supporting that. We had to time our breaks around theirs so we could get in and out of the gate. Did get some cool pics but y'all are going to have to wait until later to see them, have strict orders not to post them for getting the opportunity to take them. Sorry. Did get some inside info, but, again, can't say anything. (I know, the suspense will suck!) But I can say, I think most of you will be pleasantly surprised! ;)" Also heard they were filming in the firing room yesterday. So launch sequence? I think so!
