Hypersonic travel, defined as speeds exceeding Mach 5—five times the speed of sound—promises to shrink travel times significantly. For instance, a flight from New York to London could potentially take just an hour, a stark contrast to the current seven to eight hours required by conventional aircraft. While hypersonic technology is not entirely new, with historical milestones dating back to early rocket experiments, Musk’s approach could accelerate advancements in this field.
