Film viewer may not be so helpful. CVs are always off in the film viewer, so torps might miss them by a mile and still give the damage in the text buffer.
It's one of the film viewer quirks.
I do like the idea of having it in-game, though. That would be awesome to watch!
Plus, it doesn't even have to be when you're dead. Just make it a non-movable gunner position. Leaves you vulnerable to attack because you can't see or hear what's going on. You could get shot down in that view.
Although I agree knowing about their impact while hanging in a chute would be extremely useful.
