Massive Spewing Jet Low Altitude...Very Creepy 5/29/22

I was at Sequoia Park in Monterey Park with the LA UFO Channel group. A few of us were talking about and wondering if Chemtrails were being done by humans. Suddenly this jet flies over spewing substance from it. Look carefully...the mist or whatever is not only spewing from wings...but also the cockpit. We have been to this park tons of times and saw many planes fly over...but never saw this...ever.
