Cockpit:

“It comes from “cock”, which was an old English term for a small boat, and “swain” which is a servant. So simply put, a cockswain is a boat servant. Over time, the title led to the steering compartment of smaller boats where the cockswain sat, then the area became known as the cockpit.”

I’ve always called it the flight deck anyway, because word meanings evolve (now more than ever), grew up hyper religious and the word “cock” seemed mildly naughty

Honestly, no one cares.
