Not the Dumbest Thread Ever At LCF...

But definitely well below even the abysmal mean over there. One of the newer members asks the old "How could an aluminum plane crash through a steel skyscraper?" After a couple of reasonable responses, we're off to Lalaland.

The best scenario would be to throw a beer can at a larger bucket or can. WTC was not a solid mass, it was a matrix with an outer skin itself. neither the 'object' or the receiver 'subject' was a solid mass, why do people always get this wrong?

Yes, that would be the "best scenario", providing of course that you could throw a beer can at that bucket at 500 miles per hour.

We get the usual "I'm don't know how to do the math, but this looks wrong to me."

So what happened at the WTC? It's tricky. WTC had a greater resistance to the plane' . The planes inertia would have been dispersed over it's total area(the dimensions of the aircraft). That needs to be figured mathematically, and I don't have the knowledge of how to do that. But what is not thought of is that the WTC also had a dispersal of it's mass, which was it's lattice construction. (The 'net' effect people always talk about). That made ITS resistance less to on oncoming/highly velocity object.


If you stuck steel column of around 2 feet in width, out of the ground about 60 feet up, embedded in concrete and fortified, with half of it's length going down in the ground another 60 feet, you would have a stable structure. Now take any aluminum plane and ram it into it at 500mph. Sorry guys, but the little plane would rip in half. The steel might bend a tad, but only that.

Now take a matrix of 50 of those said steel beams, and try and run an aluminum plane through it, like when we played "red rover red rover" as kids. What do you think would happen then? Plane= Buh BYE

Of course, he is getting into no-planer territory as he realizes:

I had a new "try this at home " test to propose to someone(even though it involves a Boeing and millions of dollars of steel). Then I realised I would be so banned from this forum for what that 'test' would propose.

I am sure that this simulation would have been edifying indeed.

Somebody else proposes a new theory:

all the columns and floors on the impact sides were dropped out of the way of the planes, immediately before the actual crashes/impacts (less than 2 seconds). if we calculate the buildings collapse times, for each second that transpired, anywhere from 5 to 8 floors were becoming "undone". so in two seconds or less, anywhere from 10 to 15 floors of building could have been moved out of the way via demolition, which is close to the number of floors the planes managed to make contact with overall.

There are some people who still have working synapses:

There are even 'water drills' which can cut through steel. ANother example of how a lower density material can overcome the higher, with velocity.

Another paint-chip eater checks in:

a commercial airliner flying 500-600MPH at less than a thousand feet is not physically possible. i'm not a "no planer" but the truth is what it is and that is the truth.

the truth is that the planes had to be traveling slower which would make penetration harder but then again the planes had helped penetrating the buildings as clearly seen in the anomalous flashes prior to both planes impacting.

It goes on like that for four pages (so far).
