These would have been very old planes by modern standards, like 60s and 70s-era jets with minimal sound mitigation. There were no rules requiring hush kits then, that all came in during the late 90s and into the 2000s.
So about 25 years ago, that was probably the last time that airport sound was a big public issue.
