"One of the things that we considered was being apprehended before we got to Japan. And the plan was that if we were within range of Japan, we would go ahead and bomb our targets, fly out to sea and hope, rather futilely, to be picked up by one of the two submarines that were in the area. If we were within range of the Hawaiian Islands—say, Midway—we would immediately clear their decks and proceed to Midway so they could utilize the task force properly."
