Thanks for that data. To play devil's advocate, how hot do you have to heat barium before it goes through a chemical change that creates nothing other than benign byproducts?
And for the record, I'm not denying that there are thousands of planes that in fact do not contain any aerosol spraying devices, and that there are likely a few people here who have piloted such planes. The argument that since some planes exist that aren't equipped with chemical delivery systems is as valid of an argument as saying that it is impossible for there to be corn in vomit, since you and people you know have thrown up for years with no corn being present. If one of those people eats some corn on a puke day, that will change. I promise.![]()
