LOL! I might have to concede that when they were in hover mode!
Another plane that had unusually loud engines to me was the A-6. I think it was those exhausts that were angles slightly outwards. I stupidly stuck my head up one time as one of those went off the waist cat and I was in the catwalk. My headgear got turned sideways on my head...
In retrospect, I remember seeing everyone duck down, but I stood there like a rube not getting it. I’ll tell you, I never did THAT again.
I was Navy, also. Aboard Big John in ‘86. I was in an EA-6B squadron. BIG, loud, clumsy aircraft.
