FAA’s supersonic plan draws fire over sonic-boom metric

The Federal Aviation Administration's (FAA) proposal to lift the US ban on civilian supersonic flight is facing significant opposition from environmental groups and raising concerns within the industry itself. Specifically, the FAA intends to utilize ‘overpressure’ as a method for regulating supersonic flights, prompting strong reactions. Environmental organizations have voiced their disapproval of this approach in recent days. Despite broad support previously expressed regarding returning supersonic travel to American skies, reservations are now emerging. The debate centers around the potential impact of sonic booms generated by these aircraft, highlighting a key metric of concern.
