Is that a round about way of saying 'I can't do physics'? Come on now - you guys are the ones saying a jet wing can slice through the steel, you must have a reason for it other than because you saw it on the TeeVee.
Where's all the math?
LOL, you can't do the math, so you ask for the math.
The WTC shell at the impact areas can stop a kinetic energy impact from an aircraft equal to 386,000,000 joules.
The impacts on 911 were 2,740,000,000 joules for flight 11, and 4,380,000,000 joules for flight 175.
Means there was no way for 11 and 175 to be stopped by the WTC shell.
This is reality, you have fantasy. You ask for the math, but can't do math. How ironic.
What are your numbers?
All engineers can see a high speed plane can pass through the shell of the WTC as designed. It is your job to show the math that a plane can't enter the WTC as designed on 911.
Did you know if the shell had been thicker, it would stop the planes? The WTC would stop a slow speed plane.
Like Flight 93, if it had crashed slow, there would be more parts that look more familiar, but it was high speed, and there were no parts you normally see because as pilots we try to crash as the slowest possible speed.
