I grew up just across the street from the SM airport and learned to fly there (thanks USAF $$) at the Claire Walters (RIP) school. As a young kid, I'd get home from school and go to the Pier Street alley, lean against the chain link fence and watch the parade of aircraft. ("Yes ma'am the dog ate my homework")
Cessna, Beech, Piper and the occasional AD Skyraider or T-33 and my favorite, the old C-124s with the distinctive loud squeal from the brakes and the guy sitting in the opening on top to clear the taxi route.
This battle has been raging since the 60's, and ironically our next door neighbor (RIP), an ex-Douglas Aircraft employee was the original leader of the anti-noise, 'close the airport' faction and attended every city council discussion and eventually got the initial concessions on the operating hours for biz-jets.
Los Angeles area has far more pressing problems than the SM Airport.
