I just posted my thoughts about "The Apple" on another bboard and now here they are as well.
I like it when Kirk says "Jettison the nacelles and crack out of there with the main section if you have to."
He was definitely referring to saucer separation. And it made sense in that situation. All Scotty had working was the impulse engines against Vaal's tractor beam. The impulse engines are on the saucer, so dumping the powerless drive section would lighten the mass of the ship with no loss of thrust, making it vastly easier to break away.
Overall I think "The Apple" was a relatively crummy episode, and it has not aged well, making matters worse.
- Kirk and McCoy don't have the slightest thought of resuscitating the first redshirt when he gets hit with poison plant darts, or of beaming up to see what can be done for him in Sickbay.
- Kirk greets a native who's trying to hide by sneaking up and punching him in the mouth without warning.
- Chekov says to Martha, "If we had to stay here, would it be so wery bad?" Well, let's see: If we have to stay here, that means 421 of our shipmates are going to suffer a fiery death in the upper atmosphere. No biggie.
- After destroying the natives' whole economy, social order, and way of life (forced to or not), Kirk is incredibly cavalier and insouciant about it. "Yeah, you've just lost your eternal youth so you'll start aging now, and your community is too small to survive as a viable gene pool, and you have no idea how much hard labor is ahead of you as subsistance farmers, but you're going to like it soon." This was Star Trek's version of "We had to pass the plan so you could see what's in it."
