Newton III in action – continued

This amazing footage of the Saturn V rocket launch for the Apollo11 moon landing mission has been put online by Mark Gray.  The video provides an extra dimension to the launch photograph in my earlier post about Newton’s 3rd law of motion.  While that picture shows an enormous plume of gas being forced out of each rocket exhaust, the video below demonstrates the heat of the gases and the effect they have on the structure of the launch pad itself.
