this is not touchy-feely stuff, this is hard science.
you have to know some things... for instance...
(1) how much air goes through a big jet engine every second?
(2) how much fuel goes through a big jet engine every second?
(3) how much water is produced when that fuel is burned?
(4) taking the answer from question (1), above, how many cubic meters does that air occupy at 35,000 feet?
(5) the water produced by combustion is evenly distributed though the volume of air that's expelled as exhaust from the engine... that's the volume you arrived at from the answerr to question (4)... would that volume be visible from the ground if the atmospheric conditions caused the water to condense?
if you guys are not serious enough to do your homework, you're not to be taken seriously about chemtrails.
Your comment proves - exactly nothing. A normal contrail can exist only at certain altitudes and under certain conditions of temperature and humidity. And Chemtrails are frequently seen at altitudes well below that of normal contrails and with greater density and frequency.
8. Invoke authority. Claim for yourself or associate yourself with authority and present your argument with enough 'jargon' and 'minutia' to illustrate you are 'one who knows', and simply say it isn't so without discussing issues or demonstrating concretely why or citing sources.
14. Demand complete solutions. Avoid the issues by requiring opponents to solve the crime at hand completely, a ploy which works best with issues qualifying for rule 10.
17. Change the subject. Usually in connection with one of the other ploys listed here, find a way to side-track the discussion with abrasive or controversial comments in hopes of turning attention to a new, more manageable topic. This works especially well with companions who can 'argue' with you over the new topic and polarize the discussion arena in order to avoid discussing more key issues.
if a big jet engine gobbles up a ton of air every second, along with a gallon of fuel, how much water is produced as the fuel is burned?
that water is mixed with the ton of air as it passes through the engine... how much space is occupied by that ton of exhaust --mostly unburned nitrogen along with smaller amounts of co2 and water vapor-- at 35,000 feet?
would such volume of water vapor be visible from the ground if weather conditions caused the water to condense? ...keeping in mind that a ton of this stuff is produced every second...
you're supposed to be a whiz at math... time to do some homework.
