NASA Sets a Record

Congratulations to NASA for setting a world record of Mach 9.6 with a successful test the X-43A.

An unmanned experimental jet broke a world record for speed on Tuesday, cruising over the Pacific Ocean at just under 7,000 miles per hour in a NASA test of cutting-edge "scramjet" engine technology.

The X-43A aircraft flew at a speed of around Mach 9.6 -- nearly ten times the speed of sound -- after a booster rocket took it to around 110,000 feet and then separated.
