There's a reason why the Concorde only few over the Atlantic Ocean: Sonic booms. If every airplane were supersonic, it'd be extremely noisy and annoying. Fortunately, NASA is working in a solution.


NASA is working on multiple experiments to develop an airplane that will not boom like Steve Jobs in a keynote. If they achieve their objectives, it will solve one of the problems of civilian supersonic flight. It will also make planes look like flying narwhals. And we are ok with that. [NASA]
