Beijing-based Lingkong Tianxing Technology, also known as Space Transportation, has successfully tested a prototype aircraft capable of reaching Mach 4, which is equivalent to approximately 4,930 km/h. This achievement places the company’s technology at twice the speed of the Concorde, which was one of the most iconic supersonic passenger jets, capable of flying at around 2,150 km/h. This leap in speed represents a significant advancement in supersonic aviation, heralding a new era of ultra-fast travel for both civilian and potential military applications.
