Cementing Relationships - S9-E3
Trivia: When someone is needed inside, B.J. tells Hawkeye to go, and says "I'll stay here with Der Bingle", referring to Mulcahy, due to him singing as he mixed cement. "Der Bingle" was a reference to Bing Crosby.
Father's Day - S9-E4
Trivia: Andrew Duggan plays Loretta Swit's father in this episode. In real life, Duggan was only fourteen years older than Swit.
Answer: The C-42 was a military variant of the Douglas DC-2. Very few C-42's were built, so it's questionable that Potter would specifically have seen that particular model, but, given his military background, it's not entirely unreasonable that he might use the military designation even when the aircraft in question is actually a civilian DC-2.
