My father was there, the photograph says to me directly. But he was also not there. Not only not visible in the photograph—which, taken from the wing, shows no hunched shoulder or flying cap to indicate the person pressing the firing button—but not there at all. Concentrating, yes; in fear for his life, yes. Supremely there, of course, while the shipboard German gunners sprayed flak at him and he dropped his powerful twin-engine airplane into a dive. But also absent, in a reverie.
