I'm in several local astronomy groups on FB. When we had the comet in the sky a couple of months ago, there were literally dozens of posts a day with pictures of airplane contrails at dusk asking if it was the comet. It actually shocked me how unobservant some people are - you've lived several decades just a few miles from three major international airports and you've never taken notice of what a plane looks like at dawn or dusk?

I have less than zero faith in witness testimony.
