Great show. Loved it as a kid.....and as stated, its Hollywood. Very easy for Vets or enthusiasts to pick apart things that the average Joe has no clue about.
I could sit here all day pick apart the original Top Gun and ending of Top Gun Maverick. Gooofy as the original is, I love watching it for sentimental reasons. But, its mostly comedy to me.....as my Wife says "Its a movie, deal with it Mr. expert"....and of course a good friend will say "It was in the script". LOL
As for the C47 thing...the military had so any variants of the aircraft modified for the same thing. Look at the UH60....most know it as the Blackhawk....some know it as a Seahawk...Hollywood would most likely refer to it as a Blackhawk so the majority will identify.
Makes you wonder about Hollywood arguing with Technical advisors/consultants when making movies...I actually heard a story about that happening during Top Gun from a well known pilot who that movie would not have happened if it were not for his book....
