Hypersonic travel refers to speeds greater than five times the speed of sound, or Mach 5. This technology aims to significantly reduce travel time, allowing passengers to reach distant destinations in a fraction of the time it currently takes. For example, a flight from New York to London could potentially take under an hour. Research and development in hypersonic travel involve advanced materials and propulsion systems, such as scramjet engines. These engines operate efficiently at high speeds, making them suitable for both military applications and commercial air travel. As technology progresses, hypersonic travel may revolutionize global transportation.
