Proof that contrails never form into clouds

[LightHorseman]

So, what your saying is it is completely ethical to fly exhaust belching, cloud producing aircraft by the 1000,s over our heads, while the military has spent millions of $'s building
engines that DON'T produce contrails.

What good is stealth, if it leaves a giant long trail of exhaust for everyone to see?

Pollution, is ethical?

could that be why stealth aircraft either operate at night, or low to the ground bellow the level at which contrails form? (also beneath the radar)

Why did you not, y'know, make your point in the first post?
