what is the trail left behind in a jets wake

Chemistry--
The COMPLETE combustion of a hydrocarbon fuel like gasoline or jet fuel
(kerosene) produces only heat, carbon dioxide, and water. However there are
gotchas like incomplete combustion, additives to the fuel, sulfur or other
contaminants of the feedstock which wasn't distilled out of the fuel, etc..
Also, when air is the oxidant, some nitrogen will be oxidized to various,
mostly harmful, nitrogen oxides (NOx). For example, the combustion of
methane in air will yield, in addition to the major products of carbon
dioxide and water, the minor products which include carbon monoxide,
hydroxyl, nitrogen oxides, monatomic hydrogen, and monatomic oxygen.
