Let's say you want to make a modification or attach something to aluminum lithium. You now have to use mechanical attachment with seals you can't weld it on.

So with rocket you're really trying to maximize the percentage of the rocket that is propellant, minimize the, the mass, obviously. (1:59:22–1:59:29)
