A rocket stage test firing by Chinese commercial company Space Pioneer ended in catastrophic failure and a dramatic explosion Sunday. Space Pioneer conducted what was intended to be a static-fire test of the first stage of its Tianlong-3 launch vehicle at a test facility in Gongyi country, Henan province, Sunday, June 30. Amateur footage captured by Gongyi citizens and posted on Chinese social media shows the nine-engine test stage igntiing and then, exceptionally, taking off. Hold-down clamps and other structures are typically used to securely keep stages in place. The stage is seen climbing into the sky before halting, apparently...

"Ah, Robert, it’s a lovely morning," says Jack Allavie, the commander of the B-52 launch aircraft. "Yes it is, Jack," I respond while running through the preflight checklist for our July 17, 1962 mission. The North American Aircraft X-15 was designed to investigate flight at hypersonic (Mach 5-plus) speeds and extremely high altitudes, and the effects of aerodynamic heating on aircraft surfaces. It was the first aircraft to fly Mach 4, Mach 5, and Mach 6—and I had the good fortune...

When Robert White shot through the sky in a rocket-powered X-15 airplane nearly 50 years ago, he earned a place in the development of America's space program that those in the field still talk about. First to break Mach 4 — four times the speed of sound. First to break Mach 5. First to break Mach 6 —more than 4,000 miles per hour. All in a few short months in 1961. Then in 1962 the young test pilot with Hollywood good looks nosed his airplane 59 miles above the earth to be the first to take a winged craft into...
