Earlier this month a tantalizing thought from Boeing was presented, as "an aircraft that can fly more than five times the speed of sound, jetting across world in one to three hours. If Boeing has any say, it'll be a reality in 10-20 years."

Reports said Boeing was looking at a future Mach 5-plus strike-and-reconnaissance aircraft.
Jeffrey Lin and P.W. Singer report now in Popular Science that there is hypersonic news from China. "A team of researchers at the Chinese Academy of Sciences have tested a hypersonic plane in a wind tunnel to speeds of Mach 7, or 5,600 miles per hour."

China stole most of their technology.   They are really good at it.

What they didnt buy from Clinton.
