| I'd have thought Americans, with their penchant for firearms, would be familiar with the effects of high speed?
A soft lead 6mm air-rifle pellet, presuming a reasonably powerful rifle, can easily penetrate through 3mm of mild steel. All it takes is velocity, say around 500mph, such as the speed of an airliner...
Can an aluminium bullet, caliber best defined as "Boeing Airliner" cut through steel beams? Erm, yes.
Would it then be utterly disintergrated and basicaly in shredded bits? You betcha.
Could it then carry on and slice through or significantly damage the much denser steel beam core? No, by that time it was aluminium confetti and wouldn't do a damn thing.
