Bob C,
You do not need to be sorry. I know the first time I viewed the video I did not see the L-R, U-D controls at the bottom of the screen, and they were kind of transparent...almost like ghost images..:grin:
I can't imagine that they use those fold-down seats during the launch because of the high G-forces during launch. My guess is the entire crew sits in the room below which I think is a complete escape module that can be blown clear of the main shuttle should they loose control. I don't think it works for explosions during launch, or burning up during reentry as we seen in the two shuttle disasters.
