Can we get an idea of when the chem trailing will be stopped?

I know it looks pretty, but its a chem-bow. Here's one I saw early this summer.

With photos from early before the chem-cast set in.

Here's an actual isolated cloud rainbow I saw over my house, for comparison.

Thank you for everything,Q Patriots.

What has been done with this movement, will be forever etched in eternity. WWG1WGA!!
