Are they the AV-8 Harriers? Those nozzles are what keeps it up

When you burn rocket fuel, you get high temperature water. That's steam. So you get "vapor trails" of steam out the back of all high speed aircraft. You get trails of steam out the back of cars too, it's just a lot less because they don't burn nearly as much fuel.

Most likely a training. Nothing big.

Also, the exhaust from a jet or rocket engine is accelerated to supersonic speed via a DeLaval nozzle. In adding this mechanical energy to the exhaust, it also removes heat from it - consequently, the water vapour coming out the back of the plane is actually relatively cool, and thus more likely to condense. Dumping heat out of the back of a reaction engine is a total waste of fuel; it's only by converting as much of that heat as possible to linear momentum, and hence thrust, that you gain anything useful.

They emit an odorless gas that causes people to spell poorly and lose their ability to communicate clear thoughts.

It sounds like he's talking about ordinary condensation trails- contrails left by jets at high altitudes. Water in the fuel condenses and freezes as ice crystals. They're man-made clouds. A set of paranoid nutcases is convinced they aren't seeing contrails left by commercial jets, but "chemtrails," a secret government project to spray the populace with mind-control drugs, etc.

"Proof with your claims please."
Yes, please do that.

Yeah, apparently conspiracy nuts think that con-trails are actually secret government chemicals being sprayed on the earth for... some reason.

Having grown up near one of the largest afb's I can tell you those are ... parts of the plane!
Oh, you were looking for mind control gas? No, sorry.
