If it is physically impossible for an airliner to bring down any skyscraper 1000 feet tall or more then the "Let It Happen" scenario can't make sense.

Every level of a skyscraper must support the combined weights of all of the levels above it. The designers must figure out how much steel and how much concrete to put on every level. The more they put higher up the stronger it has to be lower down to support that weight and driving up cost.

So why aren't Truthers demanding to know the tons of steel and tons of concrete on every level of the building? This is important for the south tower since the 80th floor had to hold the weight of 30 floors. How much steel would that take? What tempetures and energy are needed to weaken THAT MUCH STEEL in 56 minutes?

Is there a conspiracy regarding the tons of steel and tons of concrete on every level of the towers? So why haven't we heard that in SIX YEARS? How can you analyze the physics of the impact without the distribution of steel and concrete thru the building? How many tons of steel can you heat to 1100 deg F in 56 minutes? Didn't the designers have to figure out what ot put on each level in the 1960s?

How much steel was on the 80th floor of the south tower?

Windsor Tower 131 ft x 82 ft x 348 ft tall
30 flrs of WTC 205 ft x 205 ft x 360 ft tall

There had to be enough steel on the 80th floor of the south WTC to hold FOUR Windsor Towers. But we haven't heard how much steel was on every level of the buildings in SIX YEARS.

The Windsor Tower didn't collapse in 18 hours of fire so how did all that steel weaken in 56 minutes? Don't steel the TRUTH!
