Ji FU quoted Letters to Star trek by Susan Sackett
Letters to Star Trek is a reference book first published in 1976. Edited by Susan …
In the original pilot we had a woman as second in command... played by Majel Barret...[NBC] would like two major changes: get rid of the woman and 'the guy with the ears'... I figured I could save one, so I kept Mr. Spock...and I married the woman, because to do it the other way would be illegal in California!
