Can a 100+ton Airliner disappear into a steel columned concret tower building?

Steel? or just metal? aluminium and zinc alloys melt at a relatively low temperature and I would expect them to be found there. I doubt that even in a demolition that there would be evidence of molten steel. Yes, a building's life may be limited but the very idea that it had explosives built into it is outright ridiculous, even moreso than the original concept.

Fact: The maximum flame temperature increase for burning hydrocarbons (jet fuel) in air is, thus, about 1,000°C—hardly sufficient to melt steel at 1,500°C.

 

Fact: There has been no known collapse of steel framed high rise buildings due to fire damage before or following the WTC debacle. The 3rd building to be destroyed (WTC 7) on that day was not even hit by anything except (possibly) some debris from the twin towers' collapse hours beforehand. It suffered some localised fire damage to a few floors. That these buildings collapsed at free fall velocity on their own footprint is ONLY possible if they had been demolished by controlled explosive demolition charges.

 

The recrystallisation temperature for steel is typically between 400 and 700 °C, beyond which it softens rapidly. It doesn't need to get anywhere near the melting point to fail under load. It also takes a long time to prepare a large building for controlled demolition, and if you did you would typically put the charges at the bottom, not two-thirds of the way up and at a time when the building is fully occupied. Buildings that are demolished by controlled demolition are stripped until they are virtually an empty shell. That certainly didn't happen here.

Have heard it postulated that the buildings were designed with eventual demolition in mind. Israeli firm had the security contract over the centre. Sounds crazy, I know, but lifespan of buildings is not now unlimited. If there is any truth in this then it could be a plus to a future buyer. As stated, WTC 7 came down with no aircraft collision and the owner deciding to "pull it " 30 mins before it collapsed in a controlled demolition. Pools of molten steel were found in the rubble of the 2 towers. Molten steel!

Utter BS!

There was no intention of a short life, the reason for the design, as I mentioned has been explained by the designer.

An interesting analysis. The First 3 minutes is just interviews with conspiracists but the rest goes into detail.

 

Some interesting points are. The fires were not tackled so continued unabated. The side of the building shown in the clip that conspiracists use shows the side of the building that had the least damage. This clip when presented by conspiracists omits the collapse of the rooftop penthouse before the rest of the building collapses as shown in this clip. During the video of the collapse we can not hear any explosions as you would expect in a normal demolition.

Love it??

Some of the modern day conspiracy theories. Flat Earth, killing of the Jews never happen, man never walking on the Moon, all dozen of them! Elvis never left the building!?

Where would this world be without the crackpots? Boring/dull most likely!?

I might need a bit of help here; I'm a bit thick. I can see the progression and the wisdom page possibly representing connecting the dots. It's the Star of David on the conspiracy sheet where I don't get the connection.

See ya later...Elvis is leaving you all to it.

I thought it was obvious, even said so in my previous post, the killing of the Jews never happened!

In what context do you state it though? That can be unclear. Nev

Fact: Elvis left us all some time ago. Or maybe that was just a rumour.

Ah yes, the holocaust conspiracy theory. What's obvious to some isn't always obvious to others. I twigged after reading your previous post which hadn't appeared at the time I was typing mine.
