Right! There were all kinds of interesting landing-party related touches in that one, from the breathing masks to the highly unusual group of McCoy/DeSalle/Jaeger - I guess DeSalle was in command - to the fact that various members of the crew go down to Gothos three separate times (four if you separately count Sulu and Kirk being abducted). Moreover, Scotty never makes it down to the planet despite hanging around in various scenes (he does request to go down, though) and Jaeger completely disappears from the episode after the first escape.
