Aircraft aluminum
The aluminum used for commercial aircraft is nothing like the soft aluminum people see in other applications. It is strong, hard and brittle - and not that much softer than architectural steel On impact, this stuff doesn't bend and break, it shatters like glass.
There is no correlation whatever between fighter planes and commercial aircraft. Fighter planes generally have very large amounts of titanium and cobolt alloys. These materials are extremely tough. They will crunch into a compressed ball before they'll break. Fighter planes are designed to withstand extreme stress in daily use.
Fighter planes are hard, dense and heavy. The only reason they get off the ground is that with engines powerful enough a brick will fly. Seeing a few come into Burbank mixed in with 737s, you can see there isn't the slightest resemblence. It's like comparing a beer can to a rock crusher.
Disclaimer: I used to be a manufacturing engineer (designing manufacturing processes) in the aircraft industry, so I have at least a passing knowledge of the subject.

Well, because . . .

It IS hard
I've never seen it shatter, though I have seen it cracked.
We use it for our shields.

Yes, aluminum can offer far superior strength to steel in ratio to weight. Yes, indeed. However, when the aluminum plane strikes the steel building, the weight of the steel is going to render the much lighter aluminum into fine metallic confetti.
Carmakers understand the heavier their cars the safer they are:

yep. And, we saw nothing like this in the videos.

Evidence please.
However, when the aluminum plane strikes the steel building, the weight of the steel is going to render the much lighter aluminum into fine metallic confetti. Evidence please. Note that video of a fighter hitting a reinforced concrete monolith isn't evidence to support your claim. Cheers, Scott.

Bah. You simply don't listen.
but then, your credibility is already zero. You have nothing to lose. Ben lived in NYC. I lived in 'Jersey when it happened, with close personal friends working in NYC.
We have MANY credible witnesses, you have - what? An assertion that there should have been 'metallic confetti'? Then you don't see it, so rather than question your assertion we should disbelieve multiple credible witnesses and physical evidence?
Go preach to those that believe the holocaust didn't occur, or that the moon landings were faked. You bore me.

Actually, that's complete nonsense.
One of the safest cars on the road is the Toyota Avensis, which is not only considerably safer than most SUVs but considerably lighter.

If heavier is safer . . .
. . . then why does the National Transportation Safety Board list pickup trucks and SUVs as the vehicles most likely to kill their occupants in an accident?
As to your metalic confetti, confetti going 400 miles per hour isn't going to just stop and bounce off the surface, it's going to keep on going.
You get a goose down pillow in your face at 400 miles per hour it's going to hurt like hell at least and probably kill you.
