There were several contributing factors that caused the uncoordination of the US strikes. Some were inherent in the US system, some were "that's just the way it goes." In at least one case, it was because a squadron leader simply REFUSED to do as he was told. Lt Com Waldron claimed he knew better than his commander where the Japanese were and he had no intention of wasting time flying to an empty spot on the ocean--and he was absolutely right. We have a year or more ahead of us before we get a look at Jon Parshall's new Midway book, but I'm sure it'll be worth the wait. Warships1 has a good Midway OoB: http://www.warships1.com/index_oob/index.htm I have a revised version that I haven't posted yet, but the one that's there is good enough for our purposes. You can see where all the Japanese carriers are, though the air group info isn't all on-target.
