Just after Pearl Harbor, both airplane and aircraft replace airship. Later on, airplane fades out in favor of aircraft.
The change is so sudden that I wonder if media received an official order.

A pretty good marker for the transition point is the 1940 non-interventionist spy serial K-7. All flying machines are airplanes or planes. The transition comes in especially handy in this episode about bombing planes stowed on ships.
Agent Pat shouts:
"Agent Z! Agent Z! There are also planes aboard the other ship!"
This would have been tricky in the previous vocabulary....
Pat: "Agent Z! Agent Z! There are also ships aboard the other ship!"
Z: "I'm sorry, Pat, your message is ambiguous. Could you elucidate?"
Pat: "There are also vehicles which rise from the ground using the Bernoulli Principle aboard the other vehicle which floats on the surface of the ocean using buoyancy!"
Z: "Too late, it already exploded."
