Suppose that I fly my ship in such a way that it is dangerously close to the edge. I plan to take a sharp right turn to avoid the edge. The template fully fits on the board, and the ship - after moving - is fully on the board. But, during the move, if you were to slide your ship along the move path, part of the ship would be off the board. Does the ship get destroyed because it left the battlefield during its move, or does it not get destroyed because its final position was fully on the board?
