The Galileo, under Spock's command, crash-lands on a hostile planet. As the Enterprise races against time to find the shuttlecraft, Spock's strictly logical leadership clashes with the fear and resentment of his crew.

A shuttle craft under Mr. Spock's command is forced to land on a hostile planet. His emotionless approach to command does not sit well with some crew members, particularly Mr. Boma who challenges Spock at every opportunity. The Enterprise and Captain Kirk meanwhile have only a short time to find the lost shuttle craft as they must deliver urgent medical supplies to Markus III in only a few days. Written by garykmcd

When the copilot of the shuttle Galileo complains that the instruments are going into chaos, Lt Boma notes that it is to be expected given the effects of the quasar. If the collapse of the avionics on board are to be expected, why is everyone so surprised when it crashes on the alien planet? In fact, why was it even launched when it clearly would be unable to cope with these effects? See more »


Dr. McCoy: Well, Mr. Spock, they didn't stay frightened very long, did they?
Spock: Most illogical reaction. We demonstrated out superior weapons. They should have fled.
Dr. McCoy: You mean they should have respected us?
Spock: Of course.
Dr. McCoy: Mr. Spock, respect is a rational process. Did it ever occur to you they might react emotionally, with anger?
Spock: Doctor, I'm not responsible for their unpredictability.

This is awfully dull, but it is a good episode for Spock as a character
6 December 2006 | by (Bradenton, Florida) – See all my reviews

For the most part, all the episodes up until this one kept Spock in the background--allowing him no room to grow as a character or have all that much screen time. However, this is definitely his episode--as he is in command of a group aboard the shuttle craft (the Galileo). And I liked how the Vulcan logic, for once, was quite inadequate to handle a situation where logic was NOT the best approach to their dilemma. He tried using reason to predict the actions of a group of savage humanoids who were like giant cavemen--or so we think, as the folks at Paramount Studios/Desilu were too cheap to show them!! Instead, you saw bits and pieces and heard about them or saw shadows, but that was all! The problem is that this episode, despite its emphasis on Spock, was incredibly dull compared to the average show. Sure it's watchable, but that's all. I think a lot of the problem was the script. In particular, the crew members seemed awfully disloyal and were like a bunch of "armchair quarterbacks"--always second-guessing Spock. This tension seemed out of place and it just did nothing to help improve the overall image of the series.
