I'm designing for all video and no viewports. Not only are the hull
penetrations much easier, but the pilot won't have to crawl on his belly
like a reptile. And the spherical pressure hull can be placed amidships,
with wanton disregard for forward visibility.

As for IR, that's an interesting idea. I think IR illumination will
backscatter just like visible light. Doesn't water absorb the red end of the
spectrum first? :-o Joe
