I don't really get it it. Making it quiet relies on making the fuselage thinner. Thus making it even less appareling for commercial aviation. Supersonics already have a small cabin and high fuel use.<p>For military jets this doesn't matter that much. And I don't really see what it changes for commercial.<p>Seems like cool tech, but I don't get why this plane has received so much attention and funding and the research on electric airplanes has been mostly dropped.
