Suicide against any imoveable target makes very little sense. While attacking a flak is suicide, sometimes it just has to be done.
Suicide in attacking a fleet, though, is ridiculous. The guys that do it often hold their bombs and/or rockets, until they can't pull off. Yet, it is really easy to hit a big ship like the cruiser, or the carrier. I know, because I do it regularly, and often I don't take a single hit (unless there's a manned 5" gunner that knows his weapon).
I have heard guys radio that their intention is to bail over the base after a succesful capture. I have never heard of anyone intentionally augering on their target. I have hit the ground myself, once pieces were knocked off, or because I took too long lining up. Still, 10 out of 13 guys sounds a bit high ratio.
