The building is between 921 922 feet long , and the distance between column centers is 10' to 10' 1" . The height to the roof edge is
71', and 77 to 78' to the crest of the roof gable.
In the sim shown below, the plane is quite low to the ground. It apparently hit several light poles, indicating that it stayed paralel
to the ground for quite a long distance. (it did not nose dive from above)
Here the cable reels are shown as black circles, the wing and lower hanging engine would have had to clear these cable
spools which stood as tall as 7 ft.
The fuselage and wings are shown to be entering on the ground floor only.
Why did they not take the tail into consideration?
The top of the tail rudder would have hit the 3rd floor even if the plane was at ground level. (which it could not have been, the engines would have
left gouges in the grass which we know were not present)
Notice here the entry point.
The "wing root" where the wing meets the fuselage is one of the strongest parts of the plane. This should have hit right where the word "column 15"
and underlying arrow are.
This particular camera angle shows the approximate angle of attack.
The official report indicates that the plane hit at an angle, with the right wing higher.
If this is so, why is all of the damage on the ground floor?
Notice in this sim, the plane is striking between the first and second floors.
The fuselage would have had to travel through the floor of the second story.
The sim showing the columns being struck, does not take this into account, it only shows the bottom floor columns and disregards the concrete and
steel floor structure.
Here is a compostie of what a 757 should look like against the building.
Here is a composite showing structural damage.
The columns are spaced 10 ft. apart.
What caused the damage to the wall on the second floor ( the top red line)?
Why is there no damage inbetween the main entrance hole and the damage to the right which is over 30 ft. away?
The Purdue sim shows the wing entering the bottom floor.
