Tornado Alley (PROG)

[woofer]

Oh I don't know... maybe because an airplane didn't slice through it and dump thousands of gallons of burning jet fuel on it.

Note: This is a flyby, nothing more. I just happened to catch your post so I figured I'd drop by and plop something on the board. Hopefully, arizona will come back later on to finish up if she feels the need to.

Most of the jet fuel in the fire zones was consumed in the first few minutes after impact, although there may have been unburned pockets of jet fuel that led to flare-ups late in the morning.

Jet fuel sprayed onto the surfaces of the typical workstations burned away within a few minutes. The jet fuel accelerated the burning of the workstation, but did not affect the overall heat released.

Page 104- While much of the public attention has been focused on the jet fuel, most of this was combusted in only a few minutes.

Page 239- The presence of high volatility materials, such as jet fuel, were instrumental during the initiation phase, but mostly burned away rapidly and (except for a few flare-ups observed in WTC 2) played little or no role later.
