I don't trust it. They will get approval and then when sonic booms disrupt nature from coast to coast they will say "it's just because the weather/it only affects a small number of people/the 3rd party contractor who supplied the data was wrong, they are gone now/the benefits outweigh the downside/think of all the jobs". Basically they'll say anything other than "oopsie we were wrong, no transonic flight for you".
