Who told you the Pentagon was made to withstand missile attacks?<quoted text>
I never saw any sign of a 757 jet.
The photos are phony, yes there were an engine but not big enough for a 757, there were landing gear but again not big enough for a 757. My questions are:
How does a pile of rubble (or an aluminum hollow structure) destroy a building that is made to withstand missile attacks??? How does a unidentified jet get near the most protected building in the world???
Is our air defense system that in-confident???
That isn't so, it was made from concrete forms, while it is pretty strong it isn't missile proof. 160,000 lbs = 72575 kg / mass
12,977,571.2 m kg / s = 93,866,952.25 ft/ s lbs of energy.
A 30.06 is 3,000 ft lbs at the muzzle so the impact was equal to about 31,290 30.06 blasts a second for 5-10 seconds duration.
or 156,500 - 313,000 30.06 bullets fired at once.
Indeed how could that bust through those concrete wall?
F = ma is how.
To put this into perspective, this is a ammo can with 192 rounds
Imagine 815 - 1,630 cans fired at once.
That about the equivalent of all the US army, at the height of the surge in Iraq all firing at once at a single target.
