If you had a video that shows it turning into a layer of haze going over the horizon then I would be convinced.
Oh wow. Ok, here we go. Nope, nope, and nope.
Nope number one. I see by asking that you don't know much about firearms and military weapons. Black powder that produces white smoke went out of use about 20 years before airplanes were ever used in combat and 50 years before WWII. You wouldn't see smoke from their guns because the Allies and Axis powers were using smokeless powder.
Nope number two. Do you know how heavy link-belt ammo is and how much space it takes up ? Those fighter planes couldn't carry enough ammo to make smoke trails that long and still get off the runway.
Nope number three. Battle damaged planes don't all leave long white trails across the sky like those. When they smoke that much most smoke trails tend to lead down toward the ground. Hence the term, "being shot DOWN". And they often leave gray, or black smoke. There's not much in a fighter plane that will burn and produce long, large trails of white.
I think that no matter what evidence your shown you'd rather believe there's a conspiracy.
