The 23rd episode of Season 2 of Star Trek, The Omega Glory, first aired on March 1, 1968. The USS Enterprise encounters the USS Exeter in orbit above Omega IV, abandoned. The entire crew had been infected with a deadly virus that removed all the water from their bodies, leaving behind only piles of crystals. Captain Kirk, Mr. Spock, and Dr. McCoy, and one red shirt Lt. Galloway beam down to the surface of the planet and discover that Captain Tracey of the USS Exeter has been violating the Prime Directive and interfering with the planet's inhabitants' war.
Although Lt. Galloway (David L. Ross) is killed by Tracey, he appears in two subsequent episodes, with no explanation for his resurrection. Lt. Uhura and Lt. Sulu appear in the episode, but Scotty and Chekov do not.
I suppose this episode is one of my favorites because of the surprise twist at the end when the character enters holding the American flag. Also, Spock uses his telepathy to call for help in a manner not seen before or since.
