Yup.
Begin rant mode...
I look at it from practical redneck experience that mirrors your more technical. Sometimes simple works well enough to get the right answer ;)
In the not so distant past before OSHA regs, people used gasoline to degrease parts. The result was flaming people in too many cases. Because of exactly the combustable atmosphere created around the 55 gal drums used as degreaser tanks. So they switched to Diesel/Kero. Result? Parts washers in semi close proximity to open flame glowing hot wood stoves that NEVER exploded.
Now the inside of a fuel tank is a lot like a garage with a diesel (petrolium) based parts washer, Enclosed. But with lots of open flame (torches/grinders/wood stoves/OIL stoves). Those sparks do not ignite the washer or cause an explosion. I have seen SHOWERS of sparks DIRECTLY hit such. No fire. No boom.
Pour a cup of Diesel/Kero or jet fuel on a white hot coal bedded campfire. Boom? Nope. No boom. Burn, but no boom.
The conditions have to be perfect. Such as atmosphere to be compressed 22-1’ish in a Diesel, in the compressor stages of a turbine etc. before Diesel/Kero/Jet will ‘so easily’ ignite.
See diesel truck in winter for an example of how hard it can be to ignite.
One cannot look at the millions of aircraft flights and conclude that by miracle, this aircraft just suddenly defied decades of experience, reality and science.
I’ve seen a crashed f16. There was a fire but there were also plenty of unburned fuel on the ground and in unbleached fuel cells.
