It seems that RFK junior likes everything but pork chops ! ! !
So are there days when there are lots of trails and others when there are not?
Then that strongly suggests it is atmospheric conditions that form the trails rather than toxic sprays.
Clouds form at different heights, planes fly at different heights, so we can only expect vapour trails (a form of cloud) to form, or not, at different heights.
Modern jet engines have been designed to minimise condensation trails. It is very rare they will produce them. Geoengineeringwatch. com has detailed info on this.
It is not the engines that cause them, it is the drop in pressure as the air passes over the wing.

Simiul.
They would be flying at different heights, commercial flights are kept well apart by air traffic control.
Who said they were commercial? They were flying convoy. Do commercial flights do that? They were very close and going the same way.
If the planes were flying at the normal cruising attitude for jets then they were 5 - 6 miles above you, it would be impossible to tell by the naked eye as to any difference in altitude of a few thousand feet.
you are good have you flown.
what is interesting is flight radar website .
Always had an interest but never followed it up. TBH, I haven't the self discipline to be a pilot and as an airline pilot friend of mine once said, the view from the office may be good, but after a while it can become just another job.
Indeed, interested discussion is the best way forward, but might I come back to later as work beckons presently.
they are not allowed to inform you of everything -- our government gulfstream is rarely visible and an odd occasion the Pilates trainers from baldonnel are visible but not every day .
It is not a fight. It is an inquiry into truth.
Re modern engines as you mentioned above, the latest geared turbofans are absolute marvels of engineering, hats off to Rolls Royce and General Electric who have developed them.
It's counter intuitive at first but transatlantic flights will tend to head north westerly as that is the shortest line to America due to the earth being a sphere, but let us avoid debating that contention once more.
Humidity is the amount of moisture that is held in the air as water vapour, the warmer the air the more water it can hold until the point is reached where the air becomes saturated and it can hold no more. We usually talk about the amount of moisture in the air as relative humidity, this is the percentage of water that is being held relative to what it can hold, hence 50% RH is where the air holds only half the water it is capable of, at that temperature.
Odd. Relatively few flights here are heading NW. It's mostly westerly. So where are they going?
The Photos of tanks and pipework that I have seen are rather obvioiusly military fuel tankers for in-flight refuelling, although it must be noted that these are only additional to the aircraft's own tanks which often serve as the main reservoir.
Wherabouts are you viewing them from?
Not sure that it would have mollified the racoon much either.
Can you look at the photos on geoengineeringwatch.com?
Yes indeed, it is (from memory) minus 30 to 40C, but it still contains water vapour, in which case it would appear as ice which gradually sublimes back into the atmosphere. The atmosphere is a dynamic system even at that height and the rate at which trails fade will depend on the air movements present. Worth noting that fluid discharged at that height could end up anywhere due to air currents, so spraying us with nasties would be a very random affair.
