Chemicals are sometimes intentionally sprayed from aircraft for non-nefarious purposes like firefighting or farming. But these are well documented occurrences and used for specific purposes. Releases of this type are from low-flying propeller aircraft, not high-altitude jets.
Absolute joke!
Yup. Drawing giant X marks the spot grids isn’t for firefighting. I’m so tired of being lied to like someone lies to a child about the tooth fairy.
