True. Gasoline is much more combustible (and more volatile) than jet
fuel. Of course regular gas is more combustible than high octane av
fuel. High octane fuel is engineered to be less combustible to help
prevent preignition and detonation with high combustion ratios.

Correct.
2) The B-25 carries much much less fuel,
Correct. An L-1011 loaded for a flight from Atlanta to Frankfurt has
over 120,000 pounds (20,000 gallons) of fuel on board. I'm not sure
about newer jumbos. A B-25 carried about 4,000 pounds (670 gallons).
Fill the auxiliary tanks, and that expands to about 5,800 pounds (970
gallons). Get rid of the bomb load and add a 3,000 pound (515 gallon)
tank in the bomb bay, and 1,500 pounds (250 gallons) more in the waist
gun positions, and you're still looking at way under half of that
L-1011 headed to Frankfurt.
3) Modern jetfuel is much more volatile than what would have been
used in the B-25,
I don't think this is true. AvGas like the Mitchell used was "hi
test" gasoline with an octane rating typically 100 or more. As I
understand it, modern jet fuel is much more similar to kerosene.
