Bloodhound SSC's hybrid motor test was successful

The Bloodhound SSC team is reporting that, earlier today, they successfully test fired their hybrid rocket motor.  Here's a synopsis:
At 4 meters (12 feet) long, 45.7 cm (18 inches) in diameter and 450kg in weight, BLOODHOUND’s rocket is the largest of its kind ever designed in Europe and the biggest to be fired in the UK for 20 years.
During the test, which was streamed live to the web, the rocket burned for 10 seconds, generating 14,000 lbs of thrust – 30 – 40,000 equivalent hp. Sound levels at the rocket nozzle reached 185 dB, many times that of a Boeing 747 at take off.
Their hybrid rocket motor uses an HTPB grain and catalyzed high test peroxide. The peroxide is pressurized by the car's Cosworth F1 engine.
