It's somewhat out of date, but I found this ~hour long podcast interview with the founder and CEO of Boom from August 2017 really informative: http://www.airplanegeeks.com/2017/08/02/463-boom-supersonic/ http://www.airplanegeeks.com/2017/08/02/463-boom-supersonic/ It goes into some of the technical and regulatory hurdles Boom is facing, among other things.
