Did You Know?


This episode contains confirmation of a much-speculated upon topic: whether the Enterprise could separate the Engineering section and warp nacelles from the primary vessel. Mentioned in Kirk and Scotty's conversation by communicator, half-way into the show, after Kirk beams down to the planet with an away team, and Scotty takes a seat in the captain's chair on the bridge. However, no starship was ever shown doing this until Star Trek: The Next Generation: Encounter at Farpoint (1987), and shown only a few times even after that. See more »

Scott: [on bridge of the Enterprise] Captain, we pulled away a little, we gained... maybe an hour... but we blew almost every system in the ship doing it. There's nothing left to try again. I guess you'll have to fire me, sir.
Capt. Kirk: [on planet surface] You're fired.
[closes communicator absentmindedly]
Capt. Kirk: 400 people...
McCoy: Jim...
Capt. Kirk: They'll die because I couldn't see a warning sign. I had to follow orders, always orders.

The Great God Vaal
2 November 2013 | by (Buffalo, New York) – See all my reviews

Alien worlds under some kind of thought control process was a popular theme for Star Trek stories. In this episode the natives are happy in a paradise where all is provided for it, that is unless they do not feed the beast. It's power source is that of the simple Eloi type creatures who live on the planet and gather fuel for it. They call it Vaal.

It's a fearsome looking dragon like statue with a mouth and a roar and defensive capabilities that is keeping the Starship Enterprise at bay. Nevertheless William Shatner, Leonard Nimoy and a few other beam down.

Inside this thing when it's at rest is just a very sophisticated computer left millions of years ago by alien creatures who wanted to keep this world a Garden Of Eden.

I'd say the prime directive was good and broken here, but all in a worthy cause.
