Supersonic test flights are coming to Kansas with a deal signed between the Federal Aviation Administration (FAA) and the Kansas Department of Transportation (KDOT). The test flights will be on the new Kansas Supersonic Transporation Corridor (SSTC), an 886-mile invisible racetrack. The planes will fly at or above 39,000 feet, which is 7.3 miles above ground, in federal airspace. The SSTC is for non-military aircraft that fly faster than the speed of sound. … The deal is a collaborative effort involving U.S. Senator Jerry Moran of Kansas, the FAA, NASA, the Air Route Traffic Control Center and the National Institute of Aviation Research (NIAR) at Wichita State University. Moran says industry forecasts show a market for up to 300 supersonic aircraft over a 10-year period. It is unclear how soon testing could begin.
