Could watch these all day and never get bored..sad theres one mission left! 4:25, the main engine floating back down to Earth...I have NEVER seen that video angle until now, so cool! Thanks for the upload.
At approx 6:50, what is the discussion about concerning "spray patterns on the forward window at SRB separation". Ground control seesm very concerned with whether some, or all, the forward windows were "sprayed".
