The story concerns a bitter woman, Dr. Janice Lester, who feels that her gender kept her out of command positions, who switches bodies with Captain Kirk.
During this time, Uhura was forced to kiss Captain Kirk.

This was during the same episode "Plato's Stepchildren" where Captain Kirk and Lieutenant Uhura shared a controversial kiss.
If Captain Kirk was a swashbuckling risk-taker (and he was), it could be argued that he was an appropriate choice to captain an exploratory vessel in an Age of Exploration.
