What, a tag-team? Z and AA??
Look, let's spell it out once more, and stop the obfuscation.
A contrail is (sometimes) produced by the passage of a jet, through air that has sufficient relative humidity (water vapor present) so that the hot
exhaust gases, disturbing this air, will result in the formation of ice crystals....these contrails bear a striking resemblance to naturally forming
cirrus clouds. This is commonly a result of regurlarly scheduled commercial jet traffic.
IF the Military is using 'chaff' as part of their various training exercises, then I would suggest that would be happening in Restricted Airspace or
an MOA. IF this is going on, then it is not a co-ordinated attempt to 'poison' any particular target, since it's obvious that high, upper-level
winds are not that predictable!!! They change, constantly!!!!!
Why to you think the various weather services send up weather balloons??
Why do you think we pilots get asked by ATC what our current Winds Aloft are? It's all to continually update the Prognosis Charts, to help the
forecasters!!! For Aviation Weather forecasting, primarily, but also for your local weatherman on the six o'clock news!!!!
Alien Abduct....., heavy stuff dropped from 35,000 feet will fall....stuff that is atomized in a spraying pattern, will act the same way clouds do!
So, aluminum pieces of 'dust', or even strips, will flutter in the winds, and disperse in a fashion that cannot be pre-determined....well, maybe if
it rains, then the heavy drops of water might bring them right down....but, I've seen rain going sideways, haven't you?
I'm just saying, if you want to cropdust, you do it from about 5 feet off the ground. NOT 35,000 feet!!
Finally, AND I WANT THIS TO BE UNDERSTOOD!!!! Commercial passenger jets DO NOT spray any chemicals, other than the normal consequences of the engine
exhausts. The fuel, Jet-A, is NOT pumped onto a jet from a tanker truck, it is pumped VIA a truck that pulls it up from pipes in the ground, then it
is metered through the truck's system and uploaded onto the airplane.
The last, best suggestion that comes up now, is..."well, something is put into the fuel"....that is NONSENSE!!! Anything in the fuel would change
its specific gravity, and would affect the Fuel Quantity systems. When we get a fuel upload, we get a fuel slip, with the number of gallons pumped
in, from the fueling operator. We then multiply that number of gallons by 6.7 (average) because one gallon of Jet-A weighs 6.7 pounds, at standard
temps. (the variance is only 6.6 to 6.8, depending on prevailing temperature). We have to have the gallons, times the 6.7, equal the weights we see
on the fuel guages...(See, fuel quantity in a jet is measured in POUNDS, not gallons). SO, the upload amount, added to 'fuel on board' at the
start, must be checked, and must be accurate, or else we need to look deeper into it....jet's quantity can be manually checked, using
'drip-sticks', from under the wings....the mechanics will do this, and use their charts to verify....
OK....so, anything foreign in the fuel, would change its density, and I explained how that won't work. Now....the temperatures in the engine, during
combustion, will exceed 800 degrees Celsius. Tell me what sort of foreign material will survive those temperatures?
ps...Zorgon has access to another retired airline pilot, who would be able to verify all that I have written here......unless they wish to continue to
