I looked at your documents (execpt below) and it indicates that DGT-2 is not actually in use. Instead there is some ferrocene anti-smoke additive that does not contain barium. Barium was only used “by some airlines for test stand operations” meaning not actively in flight.

Of course just because they don’t admit it publicly doesn’t mean much, but due to the scale of the chemtrail program and widespread detection of barium I suspect barium is added to a commercial additive.

If you read this section of my paper:

Although the “trade secret” ingredients are well protected by the manufacturer, a recent study contracted by the EPA [10] and other sources strongly imply that these ingredients are salts of barium and/or calcium. The EPA classifies this dinonylnaphthalene sulfonic acid, barium salt as a “HPV” (High Production Volume) chemical, meaning it is “produced or imported into the United States in quantities of 1 million pounds or more per year [12].” This same study reports that “Based on the available toxicity results, dinonylnaphthalene sulfonic acid, barium salt appears to be the most biologically active member of the [dinonylnaphthalene] category [10].”

It’s definitely not a smoking gun admission that stadis-450 contains barium, but it certainly means it could contain barium. If you know of a way to obtain a sample of stadis-450 please let me know. I will have it tested.

Some of the commercial airlines use CI-2 (manganese) or Apollo DGT-2 (barium and manganese) additives for their test stand operations (reference 28). Tests conducted by the Navy and others resulted in the selection of Arapahoe Ferrocene (dicyclopentadienyl iron) as an effective smoke suppressant fuel additive. Ferrocene is only used during the test stand operation of jet engines that are the worst “smokers” (reference 29). Recently (1986), cerium octoate was found to be superior to ferrocene, and testing is underway to approve the use ofcerium octoate in specific engines during test stand operation.

Ferrocene was chosen by the US Navy (and subsequently the US Air Force) as the preferred smoke suppressant additive because it and
its combustion products are nontoxic, it is cost effective, and causes no long term damage to the engines.

I couldn’t see how you reached this conclusion:

Although the “trade secret” ingredients are well protected by the manufacturer, a recent study
contracted by the EPA [10] and other sources strongly imply that these ingredients are salts of
barium and/or calcium.

I read the document carefully and see nothing to suggest that EPA study implies that the trade secret ingredients in stadis 450 are barium salts.

Are you aware of Apollo DGT-2, an anti-smoke agent that is added to jet fuel, and is a mixture of barium and manganese?
