Side note:
The Galileo Seven was one of the most beautifully filmed episodes.
Any thoughts about chain of command and the roles the officers should have done...for example, technically, Scott was second in command or Spock's de facto first officer. As much as I love the Scotty character, he should have lowered the boom on those others that were being disobedient and present a unified front with Spock. I guess he was too preoccupied with the shuttlecraft repairs which was his primary job per Spock's orders.

At least the two command gold shirts followed commands and dutifully died in time to reduce the takeoff weight.

Also, McCoy and Boma should have been reprimanded...then we may have avoided the same problem later in
The Tholian Web.

Since both are blue shirts, perhaps there is a less stringent code of behavior for those in the Sciences branch due to the combined services structure, after all, you wouldn't want Starfleet scientists saying "scientists have always been the pawns of the military".
