" Throughout the Pacific, one could find an illicit trade in “torpedo juice,” the high-proof fuel used in torpedoes. Beer was usually rationed at two cans a week. When a larger quantity of beer was obtained by backhanded means, it could be chilled by taking it to high altitude for thirty minutes. Pilots would provide that service in exchange for a share of the spoils. "
