Concorde got a pass because it was British and even then it was controversial. Boom will still have to meet all noise pollution rules now and in the future. Noise rules are designed for normal passenger aircraft, they will not get any exceptions. I don't doubt that they can make something much quieter than Concorde but can they make it as quiet as subsonic aircraft?
