Does anyone remember which original TV series episode it was where Kirk was communicating with either the Enterprise or another ship and stated something to the effect it is all a “green light” which was really a code word for in trouble so the Enterprise was taken over remotely? I’ve searched and searched and can’t figure out which episode it was. Please help me solve this mystery.
. So it was a clever way to alert the Enterprise, but makes it sound to "the bad guys" that he's telling them everything is fine.
