> The jet fuel accelerated the burning of the workstations, but did not significantly affect the overall heat released.

FEMA estimates that each plane was carrying about 10,000 gallons of jet fuel at impact, that about 3000 was consumed in the initial fireball, and that perhaps half of what was left flowed out of the impact area. That leaves about 3500 gallons that burned inside each building. That's enough energy to lift a 150+ ton plane over 30,000 feet in the air and propel it more than 1000 miles at over 500 mph. If that much energy "did not significantly affect the overall heat released," then what you're really saying is that the energy released by other sources was absolutely enormous.
