> I went to General Dynamics and was given a 6-inch section of the Shuttle leading edge of the wing. It was so heavy, I could barely hold it with one hand. Then the manager there gave me a section, same size, of the new carbon-carbon composites, and it was light as a feather.
Huh? The leading edge of the shuttle wing has *always* been a thin CC shell structure.
He told me it was from the leading edge of the wing and it was incredibly heavy, as opposed to the same section of carbon-carbon for NASP. That's all I know. Define it as you wish.
