More fighter pilots died in automobiles than in airplanes. Fortunately, there was always some kindly soul up the chain to certify the papers “line of duty,” so that the widow could get a better break on the insurance. That was okay and only proper because somehow the system itself had long ago said Skol! and Quite right! to the military cycle of Flying & Drinking and Drinking & Driving, as if there were no other way. Every young fighter jock knew the feeling of getting two or three hours’ sleep and then waking up at 5:30 a.m. and having a few cups of coffee, a few cigarettes, and then carting his poor quivering liver out to the field for another day of flying. There were those who arrived not merely hungover but still drunk, slapping oxygen tank cones over their faces and trying to burn the alcohol out of their systems, and then going up, remarking later: “I don’t advise it, you understand, but it can be done.” (Provided you have the right stuff, you miserable pudknocker.)
