True, but that isn't what forms the contrails. The water formed by the
combustion process vastly exceeds will little was absorbed into the fuel.
That is the concept of importance. :-)

Man, this keeps going round and round.

"I" originally said that the fuel absorbs water, but that that is an
unimportant part of the contrail contribution. "I" originally said that it
is the water produced through the process of combustion, that was
responsible for forming the contrail.

"I" pointed out that the round engines of the WWII bombers produced a good
contrail while burning gas, so that proved that it was combustion making the
water vapor.

Somewhere along the line, someone got into a discussion, as to if jet AQ
would absorb water, or not, and "I" said that it did, but "I" somewhere
slipped with the name, as to if it was hydroscopic or hygroscopic. I admit
that "I" made that mistake, but still "I" claimed that water absorbed in the
fuel is not important, since the trails form from water being formed as the
result of the combustion process.

I don't expect you, or anyone else to go back and look up what I originally
said, as it is not all that important, but if someone does, the proof is
there.

I hope that this puts to rest "MY" role in the great contrail debate. Case
closed? Please?
