The Facts on the SR-91 Aurora: Former Lockheed Martin Skunk Works director Ben Rich clarified that "Aurora" was simply a ...

Atlanta-based startup Hermeus hopes to develop a passenger airplane capable of reaching Mach 5, or 3,000 miles per hour, but is the prospect of building a hypersonic successor to Concorde merely a ...

Allegedly developed in the 1980s as a successor to the SR-71 Blackbird, the Aurora was rumored to be capable of speeds over Mach 5 and altitudes of 90,000 feet.

London to Sydney would take just four hours in the Skylon space plane – which could be flying by 2019. ... The Concorde, for example, flew no faster than Mach 2. According to researchers, ...

Security classification guidance will only allow us to say the speed is greater than Mach 5.” Based on these remarks, some analysts have speculated that the SR-72 could actually double its ...

But a much lighter paper aircraft would slow to Mach 6 earlier in its descent—at altitudes of 62 miles or so, where the air is thinner. As a result, the aerodynamic heating wouldn’t be as severe.

They beat the previous record of 252 feet, 7 inches (77 meters) achieved on April 2022 by a trio in South Korea. Prior to that, the record had not been broken in over a decade.

Partnering with the Department of Defense, the U.S. Air Force is planning to build an airplane that travels at five times the speed of sound (about 3800 miles per hour), or Mach 5, going from New ...

According to Ruble, the airplane is named Mach 5 because hypersonic vehicles travel at speeds over Mach 5, which is five times the speed of sound. On the day of the attempt, they achieved the ...

For those looking to create their own record-breaking paper plane design, the feat is not impossible, but may take some time (and skill). “Mach 5 flies best at high relative velocity, but to ...
