They sprayed all day today. They must be using UAVs. There is no way they can spray that much without pilots talking. I saw about 12 planes within 30 minutes,

Here are the pictures and videos.

Watched him thru my scope.
It was one 767, white(lt gray) minimum N number size, 4 nozzles, wing tip and inboard. Back and forth all morning 8 miles apart.
+30-40,000 feet.
ATC Aurora cleared airspace and had a hard ceiling for someone special.
Military/agency ops do not leave the transponder on for this kind of thing.

Nice pics!

Do you have a link where I can find that information out too?
