Probably referring to the divebrakes open AND the shadows indicating
light coming from beneath the glider. However, Bickle said he was
freezing at that point and couldn't hang around up there to enjoy the
view. As for the shadows, late in the day, the sun would be low enough
to cast those shadows.

Hmm, was that flight done very early in the morning? If so, then the
shadows are coming from the wrong direction.
