So turbo fan engines cause lots of water vapor but not gasoline or diesel engines? Why so? Is it the composition of the jet fuel or something else?

Gas and diesel engines crtainly make a lot of water vapour too - that's the white "smoke" that comes out the back of your car on a cold morning.
But usually these engines are operating at low altitude and moderate temperatures - so it doesn't last long if it lasts at all.

The last time I was pumping white smoke out the tailpipe was from loosing oil into the cyclinders and ended up destroying my head gasket. I guess oil has more hydro-carbons per molecule than 95 octane gasoline....
Anyway yes white smoke can come out occassionaly on cold, damp mornings during the winter without any mechanical problems....just not so often where I live....so I forget about it!

On days that the trails are bad. I can see them from horizon to horizon. Even if they are "Aersol Spraying ". What size tank would they need to cover miles with trails? To me the amount that apears to be pumped out is thick, wide and incredibly long.
Thats assuming they are cruising at 30k plus feet, i'm seeing it from almost 5 miles away. Thats if they are flying directly over head.

lol - yeah I've had smoke like that occasionally too! But clearly you know what I mean - I wish I lived somewhere it was warm enough for it to be rare!

Let's forget op specs and SOPs and such and get down to the job of designing an aircraft to fit the mission profile that fits witness statements. WEIGHT CARRYING CAPACITY. Photos show trails that are about the same size as one half of one horizontal stabilizer on a Boeing 757. Full span of the horizontal stab on a 757 is 49'. So we have a trail 12.5' in diameter. So the cross section area is 6.25^2 * pi, or 123 square feet, or 11.4 square meters. Witnesses describe trails that go from horizon to horizon. Line of sight from 40,000' is 265 miles each way, or 530 miles, or 853,000 meters. So the volume of the trail is 9,724,000 cubic meters. To get enough opacity to be clearly visable from 40,000' away, you would need on the order of 20% by volume of the sprayed substance. Since most claim it's aluminum (Al), let's use that. So you need 1,944,800 cubic meters of aerosolized Al. For ease of doing this stuff in my head, let's round to 2 million m^3. Since density is given in grams/cubic centimeter, we multiply 2.8 g/cm^3 times the volume of the Al and get 5,600,000 grams or 56,000 kg. Now pictures of "chemtrails" often show four trails being left, so to leave 4 visible trails of Al from horizon to horizon, you would need to haul 224,000 kg. Since cost is always an object in aircraft design, we would like to use something already flying as a starting point. Oh-Oh - big problem. Nothing flying today can haul that payload. A 757 maxes out at 114,000 kg. The C-5, although much bigger, is limited to 118,000 kg. The king of the heavy lifters, the Russian Antanov An-124, can go a hefty 136,000 kg. Houston, we have a problem. SIZE. We need to carry 8 million cubic meters of the stuff. That is, if the particles are compressed to a solid, a block measuring 200 meters on each side. Drat! Another problem. the 757 interior is only 36 meters long and 3.5 meters wide. And we need an aircraft cabin 200 meters long and 200 meters wide. Maybe we should talk to the Russians. Nope, no help there. The Antanov cabin interior is also only 36 meters long. WING LOADING. To be able to fly and not have the wings fall off, we need to keep wing loading, that is the total weight of the beast divided by the wing area, at about the 700 kg/m^2 level. The 757 is 661 kg/m^2. If the empty aircraft is really light, let's say it can carry its own weight, and the only thing I've ever flown that could do that was the Douglas A-1 Skyraider, gross weight would be about 450,000 kg, so we need about 650 square meters of wing area. In order to operate at altitude we will need an aspect ratio (span/chord) length of 8 or so. So we use the formula 8x*x=650, and see that we need a wing span of 200 meters and a chord of 25 meters. Holy embiggenate Batman! That's 600 feet plus change. That's four 757s wingtip to wingtip. Or maybe I should say winglet to winglet if we're talking the 757-200WL or 757-300 aircraft. Has anybody noticed a 600 foot long, 1200 foot wide(including cabin), and 600 foot tall behemoth cruising the friendly skies lately? Living an empirically based reality is such a buzz kill.

I think people are under the impression that it would be easy for a fully loaded passenger jet to carry these extra bottles of cemtrail making goodies,
