Scientists solve speed surprise in stratospheric stunt
Scientists say they've figured out why an Austrian who became the first skydiver to break the speed of sound fell faster than the drag of his body should have allowed.

It was a staggering feat, a car that went faster than the speed of sound. On October 15 1997, Andy Green travelled across the Black Rock Desert, Nevada, in the Thrust SSC at 763.035 mph, or Mach 1.02. Two decades on, that ...
