haha.. btw, this be your 2nd post. First post. Though you don't seem to pose an opinion, so I'm just poking fun.

I think the second plane hit higher up cause the pilot saw that the first tower hadn't fallen over.

Then... when a tower falls I immediately think this.
"That's a controlled demolition.

In actuality, the second plane hit lower than the first plane. And it didn't even strike the middle of the tower like the first plane. It struck more off to the side missing the majority of the core, thus causing less structural damage to the south tower compared to the north tower:

Thanks for posting your story.

Why is it so hard for anyone to understand the pancake effect of the floors smashing down on each other with the building giving way underneath due to the sheer weight.

Killing 2 birds with one stone. You know it was part of possible scenarios for a long time (plane + skyscraper).
The controlled demolition would then be a matter of precaution more than a conspiration. And I could bet that insurers had something to do with that. It's clearly not something they would want to make public because in case of an emergency, there's no time to prepare a controlled demolition, and that would imply that the explosives were already in place. Try to explain that there are explosives all over some high buildings to prevent further collateral damage if their structural integrity were to pose an immediate risk to the surroundings.
Like casinos, insurers bet securely on the future using statistics at their advantage. Limiting the damage would also limits the cost, so some prerequisites would be required from the insurer before accepting a contract of that magnitude.
And I'm also sure that since then, insurance payments increased more than a little.

Source: NIST
NIST’s findings do not support the “pancake theory” of collapse, which is premised on a progressive failure of the floor systems in the WTC towers...

you all keep going on and on about how it looked like a controlled demolition

Has it not occurred to people that the loud bangs that they heard *moments before* the buildings fell weren't bombs exploding but rather the floors up above smashing down on each other?

They were made to withstand this impact were they??
The structural analysis carried out by the firm of Worthington, Skilling, Helle & Jackson is the most complete and detailed of any ever made for any building structure. The preliminary calculations alone cover 1200 pages and involve over 100 detailed drawings. The building as designed is sixteen times stiffer than a conventional structure.
Like many modern structures and buildings, the WTC Towers were over-designed to withstand weight distribution in the event of structural damage. According to calculations made by the engineers who helped with the design of the Twin Towers, “all the columns on one side of a Tower could be cut, as well as the two corners and some of the columns on each adjacent side, and the building would still be strong enough to withstand a 100-mile-per-hour wind.” As well, “Live loads on these columns can be increased more than 2000% before failure occurs.”
NIST Report, Appendix Q
Port Authority documents indicate that the impact of a Boeing 707 flying at 600 mph and possibly crashing into the 80th floor had been analyzed during the design of the WTC towers in February/March 1964. While NIST has not found evidence of the analysis, the documents state that such a collision would result in localized damage only, and that it would not cause collapse or substantial damage to the WTC towers.
“Our analysis indicated the biggest problem would be the fact that all the fuel (from the airplane) would dump into the building. There would be a horrendous fire. A lot of people would be killed… The building structure would still be there.”

I'd like to see this research since you have said they were designed with this in mind?
