I worked outside for 45 years, witnessed all kinds of bizarre anomalies in the last 20. I watched planes criss cross a beautiful blue sky turning it into a grey mass in less than an hour. Then watched a bunch of coworkers who were freaking out get handed a flight radar app, tell each other they're just passenger planes and never give it another thought. It's just another reason I have very few real friends, I can't tolerate the stupidity anymore.
