"Fifty years ago today, on March 23, 1973, Alexander P. Butterfield, the Administrator of the Federal Aviation Administration, issued a rule that remains one of the most destructive acts of industrial vandalism in history.
... The rule imposed a speed limit on US airspace. Not a noise standard, which would make sense. A speed limit."
Imagine how quiet hypersonic planes would be now if the rule had been a based on loudness instead of speed. I imagine getting from LA to NY in an an hour in near-silence... That would be awesome!
