The brunette is Majel Barrett Roddenberry, wife of Gene, voice of the Enterprise computers, originally the brunette "No. 1" in the pilot episode, second in command to Capt. Pike, and finally the blonde Nurse Chappel in the production. The pilot had Spock, but no Kirk and no McCoy, and was later split across two episodes as a flashback for Spock, in a very clever solution to a scheduling issue.

The blonde is the incredibly hot (oh my youthful infinite lust) Yeoman Janice Rand (Grace Lee Whitney).

The loser on the right is the first person to take a shuttlecraft to another celestial body. The shuttlecraft was called "Eagle".
