Ironic that the stewardess is trying to vet the doctor by giving an anatomy error, and while doing so speaks of "an air pocket." There is no such thing, and a real stewardess would know this and refer to it as "clear air turbulence." Makes her suspect, not him! 

And that opening chatter from Scotty about "Jolly Green Co-pilot" and such? "Make like this is the army and move!" Ouch. Some very bad writing in this episode.
