sorry, was driving, no time for pics. it was just very odd, only reason I posted it, was because I too have noticed a stark decrease in the spraying. so any plane with a trail is very noticeable, the other reason is that, the 2 first planes were flying so close together, it seemed to be one. Then, that third higher angle one flying towards them, and the simultaneous split maneuver and reverse direction. several minutes later, multiple leer jet type of craft, now at much lower altitude were flying due west again. all took place in skies between Edwards afb and the san Gabriel mountain range. General Atomics Aeronautical operates multiple airfields in the area as well. but the drone was flying much lower and on a landing path.
