I enjoyed the episode, possibly more than the last couple in this season. I found Stan saying his briefcase was moved a half an inch on his desk amusing, and how Steve and his friends thought getting to peep in a girls' shower was reward for a high score. The stuff in the airplane was fun too, especially how Roger imitated Stan. It's actually pretty hard for one actor to play a character imitating another character while still sounding like the original character (see "Rabbit Fire"), but Seth pulled it off, I thought. I also liked how the safety official said he'd kill a kid every hour (IIRC) unless the missing "baby" was brought forward. Nice twist there.
Planes can't take off if things aren't kosher in the air. This can include suspicious aircraft.
