So I live in rural Northern Illinois. NOT Chicago (south of). Not sure what’s up with aircraft but I seen so many leftover jet trails at one time this morning...more than 20. And at the same time there were 5 planes of some kind (way to high to even see a plane) making jet trails in the sky. All of this was at the same time. I’m lucky if I should see 1 plane making a trail a day. This much...not normal.
