shot you can see how the plane has hit the building - wings have sheared off and the body of the plan has continued through the inside of the pentagon as indicated by the burnt roof above where the plane continued
its interesting to see that vertical shear at the front of the impact site. i cant explain why all the upper levels would have sheared away like that without anything to cut through them. the plane was at ground level so yeah cant explain that
all the fuel onboard - if the roof was burnt like we can see it is but the fire was limited to the path of the plane and immediately surrounding it then i guess we can only assume they have a killer sprinkler system at the pentagon. maybe the building is built from super flame resistant shit. probably. that combined with good sprinklers limited the spread of the fire
i see b3t3k's thread about the missing money - no idea about that - its probably true
