As I have said more than once the kinetic energy of the impact covers that. remember 4MegaJoules at 500MPH
A missile is not meant for penetration it goes in and detonates most only penetrate a few inches past their length (based on timers and electronics) then explode.
Period.

Well that would be cool if you were an expert but your not!
We will talk again when you have a PHD on relevant subject matter. In the meantime I'll listen to structural engineers and architects period!
Oh yeah and welcome to ATS by the way I hope you enjoy your stay and find it as fascinating as I do.
PEACE
SLAY

If you can convert freely between the two for purposes of mreasurement they can be used to illustrate the same theory.

I was only pointing out that your units were for force when you were calculating energy. Yes, you can convert between the two, but you actually have to do the conversion.
As far as a composite deck. I'm not going to argue. I know for a fact that the word "composite" means it acts together.
"Composite construction usually refers to a construction method in which a cast-in-place concrete slab is bonded to steel beams, girders, or decking below, such that the two materials act as a single unit"
Civil Engineering Reference Manual 10th edition First sentence in composite structures section.
At the site, at Rifle Camp Road and Washington Drive near the Great Notch Reservoir, Federal, police and fire investigators sifted through the remains. The parts of the plane were scattered beneath trees, shrubs and rocks, and the smell of jet fuel permeated the air. The residents of nearby homes and the condomnium complex said the explosion rattled their homes and the flames lighted the early morning sky.
1 joule of energy = 0.7376 ft.lb
1 foot pound = effort to lift a pound a foot = 1.3557 J

Like how many plane crashes you been to? Guess dont see too many from mommy's basement?

One of the many cameras around the outside perimeter of the Pentagon:

To your other comment; rusted steel inside the weakened concrete.
WOW! Just to think that the amount of fuel onboard didn't really explode as much as I thought.. with ONLY 1 Engine putting out .. hmmmm.....a fire ?
Looking at the explosion today of the FEDEX jet.. all i can think of is.. the Penta-lawn !!!

The question is pretty simple.
How large is that Fire Engine? I'd say it is probably a little shorter than a school bus, but that would be a fair comparison. 30'
Scale it yourself. The fire engine fits in between the undamaged area in the fence and the untouched outbuilding roughly 3 times. 90'... For argument's sake, I'll grant an extra 10 feet to make it an even 100' span of an area that the plane possibly could have hit and then dissentigrated into (coincidentally without doing any damage expected to the left of the hole in the building).
How wide was the jet? It was like 135' in width, if I remember correctly.
And all of that is aside from the fact that we don't see any damage to the lawn or a single trace of what would be expected to be seen at a plane crash. Something like this... news.bbc.co.uk...
So yeah, the Pentagon was hit by a cruise missle. Like this. www.serendipity.li...
