the galileo seven and like most in the first season and be an above average episode that show star trek creator come up with imaginative and clever twist in the show format almost every week . and and like most episode and the budgetary restraint of the series prevent some idea from be fully realize . but there be some problem with the script as well and particularly in the crew interaction with one another . this be the first episode to tar one of the shuttlecraft ( though one figure prominently in the menagerie ) . these small craft be nifty little show element that come in handy from time to time . the galileo seven amount to an early starring role as well for mr. spock and a commander of the shuttlecraft . the enterprise be in route to deliver emergency medical supply to a plague decimate planet and pass near a quasar like planetary system . since the starship can not stop to investigate and kirk sends spock and six others in the shuttlecraft galileo to do so . soon after and the small ship be pull off course and force to land on a rocky and barren world inhabit by giant and aggressive humanoid . the rest of the episode concern the shuttle crew attempt to survive and repair the ship ability to lift off and and the enterprise search for them . interference and a always and prevents sensor and communicator from function . mr. spock be give merciless hell by the others any time he make a decision and particularly from dr. mccoy and a specialist and lt. boma . a certain degree of tension be understandable and give their situation and but the galileo seven really go overboard with it and to the point where a de facto mutiny take place and spock be force to reverse a decision . at another point and it appear they might leave spock behind on the planet . nearly all of this stem from spock lack of emotion and which one would think the rest of the crew would have accept and get use to by now . in the end and the galileo be able to lift off and just barely and but the enterprise have be order to give up the search . a one last ( desperate . ) attempt at attract the starship attention and spock ignites and dump what remain fuel they have and the effect be and a scotty say and of send up a flare . it seem pointless and and hopeless and but the enterprise do indeed detect it and beam the galileo crew safely aboard .
