At 1:27 of this clip from Pearl Harbor (2001), Japanese bombers are flying over teenagers somewhere in Hawaii playing baseball.
The Japanese machine gunner then gestures his arms vertically, but why? He doesn't appear to be waving as a greeting.

Essentially, the waving of the arms is meant to imply "get down"...out of harms way from the attack that is forthcoming.
I suspect that this is intended to show that the attack was aimed at military targets and that even Japanese airmen/military weren't above showing some humanity.
