Amount of fuel in outboard tanks = 0.00 gallons
Momentum of fuel hitting corresponding columns = 0.00 lbf-s
Pressure = 0.00 psi
Impulse = 0.00 lbf-s
Damage = None
I'm facepalming at myself for not initially realizing that Bardamu was confusing perimeter and core damage at first, as well as for Bardamu for not comprehending a damn thing about Ryan's presentation. For starters:
Yes, I've been using the top diagram showing the observed damage. The black dashes show the damaged areas where columns are not broken. You can see that a section of the right wing that was carrying no fuel would have to break through columns, a spandrel and a concrete floor.
Christ... One more time:
R.Mackey's "Some Basic Physics of 9/11" slide 21 said:
NIST provides pressure-impulse curves required to break typical WTC core columns...
ibid said:
... Demonstrates that, at this speed, fuel alone can plausibly fail core columns
Hasn't it occurred to you that Ryan wasn't discussing damage observed to the perimeter structures, and that he was modeling damage done to
core columns? Do you realize that you're citing an image labeled "Base case impact damage to the WTC 1
exterior wall" to challenge a case Ryan built about the
interior damage? Ryan's whole point was that we can see from the impulse calculations that the
core columns were what could have been failed by the fuel alone. All the info Ryan lifts from NCSTAR 1-2B was from a section titled
"10.5 SIMPLIFIED ANALYSIS OF CORE COLUMN DAMAGE". His entire model is based on what the fuel cloud could have done when it hit the interior structural components.
Furthermore: It's a
model. The idea was to show that a single component out of the entire system was sufficient to account for damage done
to the core (looks like we need to continually point that out to you; should have realized that before), which means that if for some odd reason several hundred pounds of fuel were flying through the towers columns by itself without a container, it could fail the cores, the point being that fuel
plus jet debris can most definitely cause
core column failure.

Folks: We have to realize that Bardamu's not only failing to comprehend points, he's also presenting red herrings as responses. I think we could've saved several pages of comments had we (I'm including myself in this) realized this earlier. We should keep it in mind from here on out.
