New laser experiments reveal that turbulence at hypersonic speeds may not differ dramatically from turbulence at lower speeds. This insight could streamline the design of Mach 5–10 aircraft and bring ultra-fast travel closer to reality.

What currently requires an entire day could become a short trip lasting no more than a feature length movie. A route such as Sydney to Los
