I think contrary to what people think, Supersonic jets is actually sustainable from a physics perspective. One of the things I'm most excited about is active flow controls on planes. The whole idea is to dynamically create laminar seperation at strategic locations. The effects of this is pretty astounding. It can drastically minimize the drag of the plane and can be also used as flight controls. I can't remember the exact year but NASA did a presentation about this and project the technology to become more prevalent by 2035. Another thing NASA is working on is to use the same jet technology to create perturbations in the wake of the plane to minimize the noise from the Sonic boom.
