How about the fighter pilot who squeezes the gun trigger and holds it for 30 seconds solid while gyrating wildly about the sky chasing the enemy, yet he still has plenty of ammo left for another ten minutes of battle and somehow he doesn't melt the gun barrel?
All dogfights take place with the combatants merely a few feet away from each other, and when the hero "flames" the enemy, he never has to fly through a cloud of burning fuel, exploding ammo, and ragged debris from his opponent's utterly destroyed ship.
Both the Japanese and the Germans seem to have flown P-47s in combat, judging from the oh-so-common "enemy aircraft's guns blazing" shots.
Renegade hot-shot fighter pilots who can't follow the rules, always ignore the CO's orders, always take unnecessary chances and put themselves and their squadron mates at risk, always manage to flame the enemy with a minimum of effort, always get the super-duper gorgeous girl, and always live happily ever after.
Not a military item, but worth mentioning... from watching countless movies and TV shows, we know that passengers on commercial airliners can always talk in almost a whisper because the cabin of a jetliner is virtually silent, as if the passengers are sitting on a couch in their parlor at home.
EDIT: Anyone remember Eastern Airlines' Boeing 727 "WhisperJets"?
