Diesel and thus jet fuel, which is mostly the same thing minus some variance in additives are both essentially kerosene + additives. Diesel is not very flammable. You can drop a kit match into a puddle of diesel and it’ll extinguish the match. The big difference is that unlike gasoline, diesel doesn’t really vaporize at standard conditions, and it’s the vapors that are so dangerous - the god old surface area effect, the same reason sawdust is much more dangerous than a solid hunk of wood.
