Nope. If it's in the atmosphere it comes down. You think that exhaust fumes from airplanes do not come down and pollute the air we breath?

And, this is wet, heavier than air.

Tell me why raindrops fall to the earth and do not just dissolve before hitting the ground. Oh, that's wrong, isn't it? I rest my case.
Nobody is pulling my leg. The person I asked is an experienced commercial pilot.

As for raindrops or snowflakes if one is in very tall building/skyscraper nearer to the top will see rain or snow falling but people on the ground may see no rain or snow if it is quite a bit warmer as the liquid will have evaporated (snow melts first) way before it gets to the ground.

That is not true, virga is rain that evaporates before it hits the ground. Very very common, I see quite a bit. Saw it more out west though.

Virga - Wikipedia, the free encyclopedia

We went through this already. The moisture evaporates and concentrates the particulate matter which will fall to the ground.

Only the WATER evaporates.

If you get a glass of salt water and boil it the water evaporates but the salt is then condensed in the glass. There is a residue.

Do you understand?

The residue is left hanging about in the air. People will breath that in. Ugh!

You're so far off you need to read some meteorology books. Clouds form when particles are in the air and water drops adhere to them (condensation nuclei). In reality you have no idea if the sterile powdered urine particles would make it to the ground or make clouds...

I have 2000 hours in small planes which is 5x-10x as much as any regular small plane private pilot would ever accumulate and never once urinated out the window, the issue really isn't an issue...let it go.

Plus I can promise you are are breathing in MUCH nastier chemicals in your drive to work than any amount of sterile powdered urine that happened to make it down from the sky from when a guy pissed out the window of his Cessna or Bonanza. Chances are if anyone did dump it out it would end up smeared on the side of the plane from the slipstream.

I know urine is sterile. I don't like pollutants circulating in the air I breath, and that includes other people's pee. You seem upset with me for thinking that way.
