I hate to admit I knew this off the top of my head, but the episode was called "Nightmare at 30,000 feet," and indeed Shatner was good. He was also good in "Nick of Time," where he plays a man who lets himself be controlled by a devil-headed fortune-telling machine.

No, Kat, it was a gremlin, not a Gargoyle. Gremlins traditionally meddle with plane engines.

Night Stalker was great, and a big influence on the X Files. As a nod to NS, the X Files featured Darren McGavin as Mulder's predecessor at the FBI: the one who named the X-Files "the X-Files." It was pretty cool!
