What does shooting a brick wall 10 inches thick have to do the shuttle? Why did you expect soft materials like lead and copper to penetrate something as hard a brick wall.

He is giving you a comparison example of the effects of impact on the strength of different materials.

Nothing, but is illustrates the strength of composite materials.

You can totally destroy a brick with the right stress at the right point, but when part of a assembly, they can withstand tremendous forces.

Just some brain food. BTW, it was not ten inches thick, but standard house bricks. It was a home made 70 year old fireplace built by unskilled labor. (the only kind we have in south Arkansas)
