Many pilots of the time were the opinion that a fighter pilot in a closed cockpit was an impossible thing, because you should smell the enemy. You could smell them because of the oil they were burning.

It's not just the physical aspect of boxing, it's the whole fighter mentality that has been ingrained in me through the years as a competitive athlete. One of the hardest things you'll ever do is to box - to get into the ring and to face off with somebody whose whole goal is to knock you out, to hurt you, and to be able to fight back.
