I had a customer recently fixated on it was demolition and not planes.

I pointed out that it would take a couple years and tons of equipment to do it. And all that time nobody saw holes cut in walls and primer cord and explosives being packed in. In almost 20 years no death bed confessions ?

They countered with the explosions seen floor by floor going down.

I asked if they thought about all the natural gas lines, propane lines, going up through the towers to all the businesses ? The electric cables from the ground to the equipment on the roof and each floor, and not extension cord size, I mean thick thick huge cables, hitting steel on the way down and grounding out each time ?

Didn't matter. I knew nothing. And what about the other building that collapsed later. I pointed out buildings have been know to collapse over time just from street traffic. And in this case two towers, over a billion pounds each. Slammed down into the ground. At least one of them cracked the planet. They had water coming in from the water around Manhattan. Don't you think that effected other buildings in the area ? Ones left standing were inspected for possible structural damage afterwards.

I suggested they find someone that was there and in one of the towers. See if that changed their mind.

And those that were there who escaped. Many have health issues years later from the dust and debris.

There is at least one Pinsider that I know who worked there. He was hungry and went downstairs to get food, when the plane hit. Or he'd have been vaporized.
He avoids the day.
