A storm isn't fire Grace...I said they didn't design it to withstand head-on high side damage. Period. Boeings didn't exsist when the towers

I clearly stated it was designed to withstand the stress of highwinds...Not fire. What you think a storm is? Just water and lightening? Or has suddenly lightening in your mind become meaning 'the building was made to withstand fire'? ROTFLMAOL!

Again...A plane hitting either building, is alot more force then the 270 mph high wind stresses the buildings were designed to withstand. The buildings would have withstood a one and a half multiplied Hurrican Katrina type of hurrican with hardly a scratch and perhaps a few broken windows...But the impact created by the force of a plane flying several hundred miles an hour was 30 times harder then that type of wind force.

The steel was bendable enough for a catagory 5 hurrican style wind...But pay careful attention Grace...It was not designed to withstand a large object flying several hundreds of miles per hour impacting it's upper floors practically head-on.

In fact, the ONLY features that were added to withstand fire damage in the building was renovations done to put fire-proofing materials AROUND the outer frame supporters in the 70's, then again in the 80's when inspectors learned about asbestos poisoning. And that wasn't fool proof because if it's degraded, broken, damaged, or soaked enough, it will fall apart and away from the supports themselves...Which is what happened in this instance.

Again Grace, slowly so you can understand...The steel used was bendable steel...Not high heat, HARD steel. So it's 'melting' points are much lower then the type of steel you THOUGHT it was made with. Hard steel couldn't be used in the upper floors that would be affected by the wind stresses, because it snaps in high winds over buildings over 20 stories unless there's surrounding buildings at the same height nearby, to break the wind's stress paths. So pliable steel is used in the floors above the 20 story mark...

That's why the pictures of the portions left of the buildings? Show bent steel still standing at the centerpoints of the buildings...Those lower portions were hard steel...But not strong enough to support the whole of the building when it collasped...Hence bent to near unrecognition. Fire didn't melt them or bring those portions down...But all the material attached to them did come off because the weight of the top falling in sheared them off of the hard steel as well as bend that steel inwards towards the collasp and fall hole.

As the films and pictures showed that day, the planes literally cut through the buildings like hot knives through butter. And that's what that building was that day, because it wasn't designed to be sliced through by large, highspeed near solid objects.
