"The most important thing to a fighter pilot is speed; the faster an aircraft is moving when he spots an enemy aircraft, the sooner he will be able to take the bounce and get to the Hun. If you have any advantage on him, keep it and use it. When attacking, plan to overshoot him if possible, hold fire until within range, then shoot and clobber him down to the last instant before breaking away. It's like sneaking up behind someone and hitting them with a baseball bat.": Duane W. Beeson, P-51 pilot, 4th Fighter Group.
