What can cause metal to melt and run off the side of a building.........???

It's not the jet fuel fires and certainly not the office fires.

What could have caused the beams and columns to melt in this way.....???

One last thought to ponder on and I'm done with this thread.

The twin towers were designed to take a hit anywhere on the structure by a 707 flying at 550 mph (885 klm/h) without fear of collapse.

Now the planes that hit the towers were 757's just a bit bigger than a 707.

BTW both buildings fell within 90 minutes.

That is unheard of due to FIRE and weakening of the structure.

Good point Longy....So how did building 7 collapse when no plane hit it and why didn't the 9/11 Commission investigate why a 47 story building collapsed in it's own footprint after the media had already announced it's collapse....How on earth could a news outlet know building 7 would collapse when the only known collapse of a skyscraper in history where the two towers that only collapsed hours earlier....Why won't the Pentagon release any pictures or film of the plane that supposedly hit the Pentagon considering every square inch is under video surveillance....Surely they could clear up any conspiracy if they stopped fuelling the flames by refusing to support their claims with any evidence....A FEMA report that is so flawed it is laughable just adds to the bullshit....If a conspiracy exists it is in the American Government who are refusing to release information that could end the speculation???

The world trade centre was built in the mid 1960’s, finite element analysis (FEA) and 3D computer modelling were of course non-existent back then.

They may have had access to primitive computers but my guess is the twin towers were designed with traditional methods, analysing Stability, Strength, Deflection and serviceability by

1. Structural mechanics, Physics & Math models

and designed to

2.National codes and standards which use many safety factors.

If anything the twin towers would have been “OVER” designed and quite capable of taking a hit from a 707 as they claim it could.

Proof that traditional methods DO WORK
.
On 28th July 1945 a B-25 Mitchell bomber crashed into the Empire state building due to poor visibility from fog.

The Empire state building DIDN’T collapse and was repaired.

The planes that crashed into the Twin Towers were 767 not 757's as i quoted above, still they are just a bit larger than 707 and the fact that they weren't flying at 550mph when they hit the towers makes the design force much larger than the actually force.

Maybe it isn't about the aircraft but about the fire weakening the structure, as everyone except the conspiraloons have been saying.


And it does happen, when the oportunity to weaken a steel structured building.
