If building 7 came down from damage, why didn't this building:

150 ton airplane compared to 500,000 ton building is the same as
150 pound person next to 500,000 pound mining truck:

The amount of fuel compared to the size of the building. Remember,
this building is made primarily of steel, glass, and concrete:

1) Tower seven fell because it was a cheaper and weaker designed truss structure building, it was not constructed in the same manner as many other buildings are.
2) A 767 holds more the 900 cubic feet of fuel, also that fuel was in a contained area which caused an explosion.
3) 150 lbs person compared to the 500K truck, is a bad comparison. If you fired the person at the truck at 500 mph, you bet that the person would puncture the grill on the truck.
A big factor in this is speed and density. The building is not that dense as its mostly airspace, the aircraft is more dense due to its frame.
So a lighter aircraft is not going to have much difficulty knocking out structure when it is literally rocketing at only a small section of the entire building, which is not that dense.
The rest of it is not even worth the time to go into.

Isn't that odd. I'd heard it was a very strong building with MASSIVE beams, built like that because it was over an electrical substation.
The building was constructed above a Con Edison substation, which had been on the site since 1967. The substation had a caisson foundation designed to carry the weight of a future building on the site of 25 stories containing 600,000 sq ft (55,700 m²). The final design for 7 World Trade Center was for a much larger building covering a larger footprint than originally planned when the substation was built.
The structural design of 7 World Trade Center included features to allow a larger building than originally planned to be constructed. A system of gravity column transfer trusses and girders was located between floors 5 and 7 to transfer loads to the smaller foundation. Existing caissons installed in 1967 were used, along with new ones, to accommodate the building. The fifth floor functioned as a structural diaphragm, providing lateral stability and distribution of loads between the new and old caissons. Above the seventh floor, the building's structure was a typical tube-frame design, with columns in the core and on the perimeter, and lateral loads resisted by perimeter moment frames.

Surely you mean 3 or 4 contained areas as per Jane's All the World's Aircraft writeup:
Fuel in one integral tank in each wing, and in centre tank, with total capacity of 63,216 litres (16,700 US gallons; 13,905 Imp gallons) in 200/300; 767-200ER and -300ER have additional 28,163 litres (7,440 US gallons; 6,195 Imp gallons) in second centre-section tank, raising total capacity to 91,379 litres (24,140 US gallons; 20,100 Imp gallons). Refuelling point in port outer wing.

What would happen if the truck were fired at the person at 500 mph? You can bet the grill of the truck would penetrate the hardest bones in his body. The physics of the two scenarios are the same. I think what we need here are detailed calculations.

Sorry, calculations needed. You must be from MIT if you are comparing the total density of the building and the total density of the plane and expecting to be taken seriously.
Originally posted by ipsedixit
That might be the case, but I'd like to see the points proven in a detailed study, because I think the plane should have been wrinkled a little as it went into the building.
I have neither the time nor the inclination to bother with such an exercise. Besides the fact that no matter how much proof is handed to truthers they will never believe a word of it, they have their theories and no amount logic will sway those theories.

And the same could be said for you plane huggers. The only difference, in my opinion, is that the truthers are correct and you are not.
Of course I built and flew them. I only serviced them on occasion.
First off, when did you build them, didn't your old man build them?
Secondly, if you recall correctly you are the only pilot I know who could not answer my basic question on hand-signals, and aircraft you claim to be certified to captain. You do know that the only reason I let you off the hook that time is because I was asked to let you off the hook.

Let me respectfully suggest that your question was so juvenile that I could do nothing more than make fun of it. But nice try.

Also, if you could tell me who asked you to 'let me off' I would appreciate it very much.
