Pentagon Attack Could Not Have Been A Missile
I gotta hand it to Henry62; he really sweats the details:
The pictures show clearly that the missile is not designed to explode upon impact against the target (in this test, a reinforced-concrete structure). It must penetrate the structure, piercing its hardened outer shell, and then detonate inside it, producing a pressure and thermal gradient whose effect is actually enhanced by the resistance provided by the structure.
There is nobody doing finer work in 9-11 conspiracy theory debunking today. Simply magnificent!
