I find it interesting that the end caps are thicker than
the hull.   I had thought that the end cap dome shape would
provide better resistance to pressure than the cylinder body
and hence be constructed of material the same thinkness or
even thinner.  Maybe this is to compensate for the ribs in
the hull.

Maybe there is another reason for the differences.

Anybody have any insight into this?

Thanks,
