The Hypersonic Age is Near

Popular Science reports: "Last March, engineers from Pratt & Whitney Rocketdyne (PWR) gathered in the control room of a high-temperature tunnel at NASA's Langley Research Center in Virginia. After a countdown, a jet of blue flame fueled by methane gas roared down the 12-foot length of the tunnel. A low rumble crept into the control room. It sounded like a rocket firing, which actually wasn't far from the truth."

These are truly amazing engines, with scary future prospects (such as missiles that can hit a target anywhere in the world really, really fast)...
