Which airliner went in at the highest angle? If you were 2 cut a carrot at a 20 degree angle, vs cutting the carrot at a 60 degree angle. Which would fall off the carrot first the? The one with the biggest angle. It was at the angle the 1st airplane hit vs the 2nd one. Thats why the 1st tower was able to survive longer than the 2nd. The last airplane 2 the the towers was basically a tuning fork. When you hit the tunning fork against metal it vibrates and shakes. Well, what would follow would be vibrations and quakes. Theirs many scenarios to this subject. All are factors to this equation.
