Of course, the CBs(?) overlook a few details:
How exactly are these chemicals dispersed?
If they're mixed with the fuel and come out with the exhaust, I would doubt anything would survive the heat of combustion intact. If the additive in question is not flammable, so as to pass through unharmed, it could only be in very small quantities lest performance suffer or the engine be damaged (think water in gasoline.) Futhermore, not every airline buys its fuel from the same source, not all jet fuel comes from the same refinery, and not all Jet Fuel is formulated the same (Jet-A, JP4, Jet-A1 are all jet fuels but are chemically different) so how does the Evil Government ensure that the chemicals are being universally sprayed?
If these nefarious substances are in separate tanks and sprayed that way, where are these tanks located? In airliners I know, the fuel tanks take up the whole wing. Also, chemicals weigh a lot. Airlines (indeed, all aircraft operators) are always concerned with weight and balance. Jet-A alone weighs something like 6 lbs/gallon IIRC. I don't think any airline would sacrifice half its range or passenger capacity for the Evil Government.
And of course, no airliner blueprints ever show extra tanks/pumps/nozzles, no weight-and-balance sheet ever accounts for the extra weight of the chemicals (nor has any airliner crashed because this weight was ignored), no airline refueler, airliner fabricator, aircraft mechanic, etc, has ever noticed the extra equipment necessary to spray the chemicals. I'm sure the pumps, tanks, and hoses need to be serviced every now and again. Someone has to be refilling the chemical tanks. Someone has to build the aircraft with the spraying equipment. Or are the airliners just sent to Area 51 for modification and preventative maintenance?
Naturally, the CBs will just say EVERYONE from the CEO down to the lowliest frontline employee of every aircraft manufacturer, airline, oil company, trucking firm, tool fabricator, and airport authority in the world is in on it.
