ST:TOS:03 - "The Corbomite Maneuver" (Stardate: 1512.2) is the first regular production episode of Star Trek: The Original Series (though this is the 10th episode to air) - this episode introduces other major characters that the first two pilots didn't - McCoy (who makes his first of many onto the bridge appearances) and Uhura (in her communications chair), as well as minor character Yeoman Rand - Chekov would be the only missing major character - he won't be seen until season 2, and Nurse Chapel is the only minor character not introduced but will be in season 1. Of especial note is the score, Star Trek is known for its wonderful compositions (from the TV series to the movies) and this episode isn't any different - indeed, Fred Steiner composed a classic score.
