It feels like we're in a time warp, GenRadek. I asked you at the start of the year to specifically quantify the amount of jet fuel that flowed anywhere... you admitted that you did not know.

A specific claim of jet fuel blowing out a basement should include an estimate for the amount of jet fuel that allegedly blew out the basement.

There was only a finite amount of jet fuel in the plane. Any damage that official government story believers wish to claim was made by jet fuel, need to also provide an estimate for the amount of jet fuel alleged to have caused the damage.

God, these truthers hold on to any little inconsistency and exploit it for their own agenda, I swear, if they found a peice of ham in the wreckage, a truther would come out and say ......

" Well its a well documented fact, that the pilot of this flight only ate turkey sandwiches, and in fact had an aversion to ham, therefore this is concrete evidence that the captain was not on board during the crash as this ham clearly did not come from his lunchbox, once again affirming 9/11 was an inside job" .

Get a f*****g grip.

If I believed in the OS and wanted to put my point across as to why *Truthers* are barking up the wrong tree, I would do this via hitting them with so much 100% pure - physical, scientific, media device captured evidence, to counter attack their theories that they would scamper off whimpering with tail between legs.

Is it not the case that the blatantly obvious lack of such debate ending tactics, not being used here, is down to nothing more than there is no such evidence available?, thus causing the hugely world wide general consensus of 9/11 being an inside job.

Hypocrisy has never been better defined than what is on offer here for all to see, we have people with genuine causes to cry foul, that are met by GL`s blowing the `Nutjobs incoming` trumpet with excessive lung bursting capacity, enforcing their beliefs with absolutely no `Look at this ffs` evidence whatsoever.

Amazing.

FYI GL's:

Jet fuel doesn't explode when falling down a shaft!

Never mind that; the amount of jet fuel available could not have expanded
through 1000+ feet of elevator shaft to produce enough pressure to blow
off marble slabs from the lobby walls.

Wow ! A truther spouting off about something they know nothing about!

Flammability limits refer to the range of compositions, for fixed temperature and pressure, within which an explosive reaction is possible when an external ignition source is introduced. This can happen even when the mixture is cold. Flammability limits are given in terms of fuel concentration (by volume) at a specified pressure and temperature. For example, the lean flammability limit for Jet A (aviation kerosene) in air at sea level is a concentration (by volume or partial pressure) of about 0.7%. The rich flammability limit is about 4.8% by volume or partial pressure. Flammability limits are not absolute, but depend on the type and strength of the ignition source. Studies on flammability limits of hydrocarbon fuels have shown that the stronger the source of the ignition stimulus, the leaner the mixture that can be ignited. Flammability limits also depend on the type of atmosphere (for example, limits are much wider in oxygen than in air), the pressure, and the temperature of atmosphere.


Jet fuel has a flammable range of .7% to 4.8% - that percent of fuel
mixed with air will ignite and burn

Operative phrase - "explosive reaction possible"



Flammability limits refer to the range of compositions, for fixed temperature and pressure, within which an explosive reaction is possible when an external ignition source is introduced.


Explosive limits



Explosion limits usually refer to the range of pressure and temperature for which an explosive reaction at a fixed composition mixture is possible. The composition has to be within the flammable range. The reaction is usually initiated by autocatalytic (sometimes called self-heating) reaction at those conditions, without any external ignition source. In practical terms, this means that the mixture needs to be sufficiently hot. Explosion limits are given in terms of a minimum autoignition temperature (AIT) for ignition of fuel injected into hot air. The minimum AIT is strong function of the fuel type (atomic composition and molecular structure), pressure, and fuel concentration. For common hydrocarbon fuels, the minimum AIT ranges between 600C (1350 F) for methane (CH4) to 200C (472F) for dodecane (C12H26). A minimum AIT of 190C (450F) is used for the purposes of hazard analysis for aviation kerosene. Note that the minimum AIT is much higher than the flash point and much lower than typical hot surface ignition temperatures, which can be as high as 900C (2000F) for common hydrocarbon fuels (Smyth, K. C.; Bryner, N. P. Combustion Science and Technology, Vol. 126, 225-253, 1997).


So a mixture of Jet Fuel in the flammable range exposed to temperature
of 190C (450F) will explode

Detonation



Detonation limits are the range of composition within which detonations have been observed in laboratory and field experiments. Detonation limits are a strong function of mixture composition, initial pressure and temperature but usually considered to be narrower than the flammabilty limits. In addition, detonation limits are much more strongly dependent on the ignition source, confinement, and the physical size of the experiment than flammability limits. The ability to initiate and propagate a detonation requires a set of critical conditions to be satisfied and despite extensive research into the subject, the limits are empirical in nature.


Under proper conditions an explosive mix will detonate

The jet fuel falling down the elevator shaft will be accelerated by gravity,
air resistance will break the fuel stream up into droplets. The long fall
will disperse the fuel droplets as an aerosol and mix it with air. All
you need is ignition source...

You lose!
