5M15 Rocket engine test fire video

This post thanks to Wired, I found the explanation of Mach disks quite intriguing. If you count the disks (7 according to Wired) and multiply that number by the speed of sound (758 mph at the altitude of the test) you can figure out how fast the the fuel is exiting the engine... 5306 mph!
