That's one scenario, but if you followed it literally, he was in the Bat until it was over the ocean. When he started out on the suicide mission, there was about 1:53 left before the explosion. He spent more a third of that time saying his goodbyes and maneuvering the Bat out of the city to the shore (remember, he exploded a building just to clear a path. That would have left him with 1:00 or less to eject. Even the fastest helicopter (which is pretty much what we could assume the Bat was) can only go just under 300 mph so at 1:00 he still would have been within the blast radius (6 miles) if he ditched before the explosion. My only conclusion is that he died or was somehow rescued by somebody very fast.
