So How Is It That the Thin Wingtips of "Flight 175" Boeing 767

simply slice through the large steel beams of the WTC (see here)?

(A good picture of how massive the WTC exterior steel beams were, is shown in the previous post.)

It's funny how Iranian plane wings actually BREAK OFF when they hit a building:



Is Iranian concrete stronger than US steel? Or are Iranian C-130's just much more flimsy than Boeing 767s?

(Here is more snark comparing 9/11 and the recent Iranian plane crash.)
