There is no fixed boundary between the water of Manila Bay and the humid air above it, only a featureless blue-grey shroud hanging a couple of miles away. Glory IV maneuvers cautiously through an immense strewing of anchored cargo ships for about half an hour, then picks up speed and heads out into the center of the bay. The air thins a bit, allowing Randy a good view of Bata’an off to starboard: black mountains mostly veiled in haze and speckled by the mushroom-cap-shaped clouds of ascending thermals. For the most part, it has no beaches, just red cliffs plummeting the last few yards into the sea. But as they work their way out to the end of the peninsula, the land tails off more gently and supports a few pale green fields. At the very tip of Bata’an are a couple of stabbing limestone crags that Randy recognizes from Avi’s video. But by this point he has eyes mostly for Corregidor itself, which lies a few miles off the end of the peninsula.
