"Lieutenant, Where's Helmsman McKenna?
He has lungworm, sir. He couldn't report to his post.
– Christopher Pike and Hikaru Sulu, 2258 (Star Trek)

As a result of developing lungworm, he was replaced at the helm by Hikaru Sulu. (Star Trek)


Background information

This character was only mentioned in dialogue.

Since lungworm is a real species that does not infect Humans, McKenna might not be (completely) Human.


McKenna's first name was revealed to be Kyle in the Star Trek: Starfleet Academy novel The Gemini Agent. The IDW Star Trek: Ongoing comic book Red Level Down revealed that he had a sister at Starfleet Academy named Amy (β), a member of Red Squad, who had also come down with the same condition.
