I lived near the old Glenview NAS in suburban Chicago during the height of the Vietnam years...and we regularly got to see all kinds of military a/c from prop trainers to transports to Phantom jets flying over walking to and from school, or just playing in the neighborhood. Got to where we could pretty much ID the a/c type just by the engine sound.
It's a real visceral sense memory --combined with an overwhelming sense of childhood wonder and fascination -- that never leaves you.
