No. It's Decker in the shuttle trying to jam it after failing to destroy it by firing on it by his starship. Kirk and Scotty manage to get Decker's ship running enough that it can be flown into the giant maw. Scotty goes back to Enterprise and just Kirk takes the starship Constellation into the Doomsday Machine, beaming back at the last possible second. (Drawn out by very convenient problems with the Enterprise's transporter.)

I was impressed that they show Kirk knowing how to do more than press buttons and bellow commands in this one. He is working with his hands, trying to fix the crippled starship. He so rarely strikes me as being competent that this was nice to see.
