Actually that's most unlikely as WTC7 is north of WTC1 and the first plane
hit away from WTC7. When WTC2 was hit from the south, WTC1 sheltered WTC7
so no jet fuel could have "sprayed" WTC7 at anytime

That's why nobody can confirm that the diesel fuel was ever a cause of any
fire in WTC7. ALL reports determine that the diesel fuel "could" have
contributed to the fires.
