And, fires make buildings collapse all the time.

Some simple facts, and some flaws in the arguments of truthers:
Your "facts" are not facts, and the flaws are in YOUR argument, not in those of 9/11 truthers

1. The building was hit by a plane far larger than the original design when the towers were engineered and constructed. To say that they shouldn't have fallen because they were designed to withstand a hit from any plane is a bit ridiculous.
False.
The maximum takeoff weight for a Boeing 707-320B is 336,000 pounds.
The maximum takeoff weight for a Boeing 767-200ER is 395,000 pounds.
The wingspan of a Boeing 707 is 146 feet.
The wingspan of a Boeing 767 is 156 feet.
The length of a Boeing 707 is 153 feet.
The length of a Boeing 767 is 159 feet.
The Boeing 707 could carry 23,000 gallons of fuel.
The Boeing 767 could carry 23,980 gallons of fuel.
The cruise speed of a Boeing 707 is 607 mph = 890 ft/s,
The cruise speed of a Boeing 767 is 530 mph = 777 ft/s.
The Boeing 707 and 767 are very similar aircraft, with the main differences being that the 767 is slightly heavier and the 707 is faster.
Since the Boeing 707 had a higher thrust to weight ratio, it would be traveling faster on take-off and on landing.
The thrust to weight ratio for a Boeing 707 is 4 x 18,000/336,000 = 0.214286.
The thrust to weight ratio for a Boeing 767 is 2 x 31,500/395,000 = 0.159494.
In all the likely variations of an accidental impact with the WTC, the Boeing 707 would be traveling faster. In terms of impact damage, this higher speed would more than compensate for the slightly lower weight of the Boeing 707.
In conclusion we can say that if the twin towers were designed to survive the impact of a Boeing 707, then they were necessarily designed to survive the impact of a Boeing 767.

2. The steel columns lost a considerable amount of their strength due to the intense heat cause by the fires inside the building. They wouldn't remain standing, as they're still bolted to the trusses and concrete slabs, and by being weakened by the fire, were simply bent down and snapped by the weight of the collapse.
Er, no, they were not. They would have been left standing below the point they snapped. The scenario that failure occurred simultaneously over all 240 columns is ludicrous. Any collapse would have been partial, sagging occurring in only some parts of the towers. It would NOT have happened all over the tower at the same time.

3. Asking for evidence of 110 floors nicely stacked up at the bottom of the rubble is like asking for a carton of eggs to be intact after being dropped 10 feet onto concrete. Stuff breaks. The farther it falls, and the more it has falling on top of it, the more unrecognizable it's going be after the collapse.
You miss the point. Large chunks of concrete would still survive. Instead, each floor was almost entirely pulverized to dust long before it hit the ground. That degree of destruction can be explained only by high-explosives.

4. Comparing temperature charts to grainy pictures of flames from the fires, and claiming that the fires must have been hot enough to constitute thermite is silly. I can light a match, and it will have several of the colors on those charts, and the flame from my match isn't going to come close to 1100 degrees.
You miss the point. The temperature charts indicate pockets of temperatures persisting at Ground Zero long after the towers fell that were hundreds of degrees higher than that reached by office fires. The official story cannot explain that.

5. Towers 1 and 2 WERE a controlled demolition. Just not in the sense of C4/Thermite/Dynamite charges. The building was weakened, burned, and collapsed. The building had nowhere to go but down. Anyone claiming that the second tower should have "tipped over" because of the angle, is naive at best. It's still being held together by the core columns, and even being weakened, still held the building together. The building simply had too much inertia to go anywhere but straight down.
But videos show sideways expulsion of steel and concrete with explosive force that cannot be explained by the accumulated kinetic energy of the floors falling above each one. It simply isn't true that eveything went straight down.
Your analysis is faulty and so your conclusion that the towers fell naturally is not to be trusted. Quite apart, of course, from the host of other anomalies connected with the Pentagon and Flight 93 that you ignore ..... .

As I said in another post what made them collapse is of little issue to me the events before hand are enough to put doubt on it. As for the A&E stuff the termite and iron orbs are compelling,
the fire temp information is good too,
the molten steel running out the side of the building as well.
