Totally agree with Admin. The more we use 'em, the more prone to danger our astros are. But as long as the teams do their job and stay focused, I'm sure the ground processing teams will make sure Atlantis, Endeavour and Discovery are in shape to make it to space and back in one piece before letting them launch. If they feel ready to support it, bring in 135 and 136. Of course, due to processing order (A-D-E), that'll put Discovery once again in the End of (STS) Flight Shuttle position. I'll go see 133 launch, and if that extension happens, I'll be there for Discovery's last as well.
