The ban was lifted for subsonic travel overland, right?
NASA is working on quieter supersonic flight, which reduces the sonic boom on the ground.

Hopefully, we get commercial supersonic flight in some form in the 2020’s.

- vilhelm_s 9y agoNot yet, I think? There was some discussion in July this year: https://www.ainonline.com/aviation-news/business-aviation/2017-07-03/congress-eyes-future-supersonic-travel https://www.ainonline.com/aviation-news/business-aviation/20... Eventually the bill passed, it has a provision that the FAA should "obtain the input of aerospace industry stakeholders regarding the appropriate regulatory framework and timeline", and report back next year. https://www.congress.gov/bill/115th-congress/house-bill/2997/text#toc-H6A36C132E87C4D5DBECD7205976B9082 https://www.congress.gov/bill/115th-congress/house-bill/2997...
- masklinn 9y ago> The ban was lifted for subsonic travel overland, right? Yes but as scrumper notes that made it inefficient.
- melling 9y agoYou are overlooking the obvious problem. Subsonic planes already existed. Even it it was just as efficient at subsonic speed, I doubt if it was as cost effective as a 737, for example. The Concorde seated 100 people, in first class. If you can’t fly at supersonic speeds, you aren’t going to spend the extra money.
