Not chemtrails. He says clearly what it is in the video which is only 42 seconds. They're doing training exercises where they spray chaff to try to subvert radar. It's not that hard to understand if you speak English.

Guy's probably had an accident by now.

Dropping chaff for what looks like bands 100s of miles long? That doesnt seem to make sense.

Don't say "chemtrails", it immediately causes anyone you're trying to convince, to tune out.

Call it "chemical spraying", or "weather spraying".

Why does it look like a 1980's vhs recording

Oh look, a retard.

He clearly says chaff. How the fuck do they get chemtrails out of that?
