New hypersonic engine could allow for travel from New York to London in just one hour

Submitted
UK scientists are hard at work testing a new hypersonic engine that could allow for future commercial aircraft to fly up to speeds of Mach 5.4. That means that someone traveling between New York and London could make the trip in about one hour, while someone flying from London to Sydney could cross that portion of the globe in just four hours.
