More than two decades since the Concorde supersonic airliner last took to the skies, NASA has been flying an experimental aircraft designed to replace loud sonic booms with a quieter thump equivalent to a car door slamming shut 20 feet away. A successful NASA flight test program could influence the design of future supersonic airliners capable of flying overland routes without rattling buildings—and people’s nerves.
The Lockheed Martin X-59 Quesst—an acronym for Quiet SuperSonic Technology—first took flight late last year and recently began supersonic test flights. But unlike with many experimental “X-plane” aircraft that may never leave restricted airspace near Edwards Air Force Base in California, NASA plans to eventually take the X-59 on a tour around the United States so residents of various cities and towns can provide feedback on the quieter sonic “thumps” it produces.
“Usually an X plane is kind of bare-bones—‘cobble it together from a bunch of parts from other airplanes and just demonstrate one thing,’” said Jim “Clue” Less, a NASA test pilot and aerospace engineer, in an interview with Ars. “We need to demonstrate that one thing, but then we need a plane that's robust enough that we can fly it all over the place and gather that data.”
