Brainsucker i think you've found something that suits your believes yet you don't fully understand the concept.
Example Number 1. By your NTIS examle if i take a 4x2 piece of wood and throw it against a thin piece of cellophane, the wood will deflect and not go
through. Reality - cellophane is pierced and wood doesn't deflect according to NTIS program.
Physics which is what the NTIS program is based on takes the assumption that the body moving has less mass (intertia) than the body being struck. If
the body has more mass (intertia) a different set of rules apply.
Newtons laws of motion explain all this.
Law 1 Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. In this case wood
(aircraft) will continue to move at said speed until another force is applied to it.
Law 2 The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as
indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the
acceleration vector. In this case, the higher the mass and acceleration, the higher the applied force.
Law 3 For every action there is an equal and opposite reaction.
If i fire a bullet into a human, the bullet will not deflect until its interia is slowed down and it strikes bone for example. The bullet is also
damaged and compressed by the sudden impact of hitting the human body in many cases. Newtons third law explains this last bit.
This also applies if i fire a bullet into a car for example. The bullet will enter and with reduced inertia start to deflect within the car as it
With the WTC planes, their inertia was enough to not cause any deflection outside the WTC, but upon hitting beams/structure inside the WTC, the
aircraft would have broken up, slowed down and stayed inside the building. Glass and other small pieces would have fallen down but due to the
overall intertia of the aircraft, it would not deflect as per the NTIS example.
Appling all the laws, the plane is flying at say 400 knots. Already it is overcoming drag to keep this speed up and will continue to do so until
thrust is reduced or is hits something. Plane then hits the building - it doesn't stop imediately. Interia keeps it going forwards due to the second
law. The third law is applied by the slowing down of the plane as it strikes the WTC the opposite reaction being the structure giving way to the plane
asorbing its impact to a degree.
NTIS deflection does not apply to this situation due to the above laws.
