"All of this can destroy a target the size of a cricket ball travelling at three times the speed of sound through the air."
Seems a bit of overkill for a cricket ball. What does it do to an aircraft? How many people outside of England (and India, Pakistan, Windies and the antipodes) know what a cricket ball is?
