I suppose that's so. The art, science, and technology of pressure

Scaled Composites a couple years ago that killed two or three people
shows that there is still something to be learned as we extend
composite construction into ksi pressures.

Building a tank that holds pressure is one thing, building one that is
shrapnel resistant is something else.
