Sorry dude, but in the 21st century, drones would blow up your WWII replicas where they were parked. There is a lot more to ownership of the skies than aircraft alone, and the USA owns the skies. You couldn’t fly a stealthed sparrow over a USA military installation, while the AF would strike with impunity from aircraft you didn’t even know was in the air.
Tell that to God, as I'm sure his sparrows are constantly flying over military installations w/o being noticed.
