I have been scanning some of my old 35mm slides and came across this one
I took out in Westlake Village, California back in November 1983. The
feathery appearance really made it look different. I know little about
weather and wanted to ask someone what it was. But, it was forgotten
about until this morning when I happened to scan it. So, can someone
tell me 23 years after the fact what it was?
A contrail. Plenty of discussion about them on usenet.
