If you asking what the cloud like streak behind high flying jets is, it's called a "contrail". Condensation created by the heat of the engines at high altitude trails along behind the aircraft. It's not residue, just clouds essentially

It could be any kind of commercial jet. The white residue is called a "vapor tail" or a "contrail," which is when the engines of the plane heat up the freezing air around it. Because the plane is so high, the altitude up there can get to 0 deggres or maybe negative degrees, and when it comes in contact with the engines that are blowing out gases that are like 300 degrees, it cause vapor. You can tell how many engines the plane has by how many trails there are side by side. Two trails means it has two engines. Four trails means it has four engines, possibly a 747.

They're still jet aircraft, and the trail is created by their exhaust (which contains water vapor) can condense and create little ice crystals or condensed water. This trail of condensation and condensed water/ice crystal is that white trail that you see, which is known as a contrail. As a side note to the previous answerer, I am generally open-minded about different opinions. However, the whole "chem-trail" argument is absolutely absurd. It is so ridiculous that conspiracy theorists can't even agree on what the "government" is doing up there. Population control, weather modification, fighting global warming, etc. Random tests have been repeatedly conducted that proves there are NO additives in aviation fuel that shouldn't be there. There is zero evidence that anything abnormal is going on.

Any jet aircraft which produces great amounts of heat and when the very high heat temperature hits the 50 below this turns into an icy gas of exhaust called contrails

Sure. It's called a commercial jet, and the white you see is the vapor trail.
Unless you're into conspiracy theory type things, and then the government has wired all commercial jets to spray out chemicals to (insert whatever here.)
Check "contrails" in a search engine to see some of the conspiracy theories.

What your seeing is the jet engines vapor trail. And Oklatom is right there is a whole government conspiracy theory about this phenomenon. If you do a web search on jet contrails you will be able to find information about this lunacy.

it is called a vapor trail -
Any commercial jet will have one, so will small fighter style jets, and concord style.
