Figured I'd toss my head in at this point and start trying to ask some of the right questions about the matter. Not really interested in chemtrails,
but mostly the oddly-shaped contrail evidence that the 'Trailer boys keep pointing to.
Important point: These are real questions that, if you have good information on, I'd like real answers to. None of that
rhetorical-question-to-make-a-point garbage here.
Also important: I have done very little special research on chemtrails. Frankly I don't think that the evidence points to this as a viable or
actively used transmission vector for chemical or biological substances. Obviously there are those that disagree, but as a result I haven't seen much
of the stuff outside this forum. IE don't assume I've seen whatever evidence from whatever site already.
And now for the musings.
I thumbed through the more recent posts in this thread just to see what was going on. I was shocked to find out that people were disagreeing on what
evidence meant. Absolutely shocked. I did notice, though, that there were a lot of posts from our regular Aircraft Projects forum crawlers on
contrails as a weather phenomenon. I personally believe this is the most reasonable explanation for the effect, but, being unnecessarily inquisitive,
I had wondered if there were other factors in such an irregular phenomenon. Even in my admittedly short engineering experience I've found that the
stuff we consider weird or irregular is usually so because there are a bunch of things that have to go into the situation to make the unusual results
pop out. So I focused on the other half of what makes con/chem/candytrails: engines and aircraft features.
It occurred to me that the contrail of an aircraft is probably affected significantly by factors of the engine, airframe, and their immediate
operating states. Lee has already pointed out the differences between the flap fairings between those on the DC-10 and those on Boeing and Airbus
aircraft, but I wanted to expand on that some more onto other parts of the aircraft with a few questions just to get some good info out there from any
that happen to know it.
There's a lot of hubbub around the "doughnuts on a rope" implying usage of chemicals. So:
-In creating these trails, how responsible are the weather conditions versus airflow over the aircraft?
-Within the fraction that the aircraft is responsible for, how much depends on aircraft shape? Size? Engine layout? Engine power setting? Airspeed?
Vertical speed? Attitude?
-Would they be affected by different trim settings on the aircraft causing non-centered control surface position?
-What role do wingtip vortices play in creating these contrail forms? Would they change from the presence of a winglet? Wing fence? Sharklet? Raked
-Within the fraction that is caused by the weather conditions, how much depends on local characteristics (Temperature, pressure, humidity, windspeed &
direction) versus global characteristics (changes in weather conditions over the area that the aircraft traverses)?
-Are there any locations which show a higher occurrence rate of these trails than others?
-Are there any aircraft types/makes/models that show a higher occurrence rate than others?
-Are there any aircraft operators or airlines that show a higher occurrence rate than others?
Now some questions about the administration for forming chemtrails, probably more suited to our brethren from another forum:
-Who, in particular, is responsible for directing chemtrail use?
-Who, in particular, is responsible for carrying out chemtrail placement?
-Who, in particular, is responsible for designing, manufacturing, and maintaining chemtrail equipment?
-Who, in particular, is responsible for supplying the chemtrail chemicals? What varieties are there?
-What is the purpose for forming these trails (may vary by who is responsible for each case)? What is the motivation behind that purpose?
-Where are the inspection, maintenance, and repair operations done on these aircraft?
-Where are these aircraft refilled with chemicals? How often do they have to be refilled?
And some questions on the technical nature of the chemtrail system:
-Are the chemicals expelled by spraying into air, or are they put through the engines with the fuel?
-If sprayed, where are the nozzles located on the aircraft?
-Where are the chemicals housed during the flight?
-Where are the chemicals housed at facilities?
-Which personnel fill the aircraft? Are they aware they are doing it?
-What concentrations are required to be effective at ground level?
-Are these components inspected by Flight Regulation Boards?
-Of the organizations who take part in this practice, which administration personnel know of it? Which do not?
-What varieties of chemical exist? Can one system handle multiple types?
-Are the chemical residues in the air visible without a contrail?
And I'm out of letters. Play with these questions for the time being if you can.
