Boeing planning on hypersonic jets for commercial flights, though the Concorde's memory lingers Boeing planning hypersonic commercial flights within a decade
"Supersonic plane to come" stories run about as often -- and are about as true -- as breaking news on either DB Cooper or Amelia Earhart. Matt
"Hypersonic Hypotheses Getting Real" " . . . a Lockheed Martin official may have let it slip that his company has already built one." An article in AVWeb https://www.avweb.com/eletter/archives/101/3897-full.html?ET=avweb:e3897:287940a:&st=email#230173
Yet another article, from Bloomberg: “We couldn’t have made the engine itself—it would have melted down into slag if we had tried to produce it five years ago,” O’Banion said. “But now we can digitally print that engine with an incredibly sophisticated cooling system integral into the material of the engine itself, and have that engine survive for multiple firings for routine operation.” The aircraft is also agile at hypersonic speeds, with reliable engine starts, he said. A half-decade before, he added, developers “could not have even built it even if we conceived of it.” He is speaking in the past tense! https://www.bloomberg.com/news/articles/2018-01-16/america-s-fastest-spy-plane-may-be-back-and-hypersonic
Google X-51 to see how the technology has progressed. That was few years ago, before the 3D printing was really mature.
