Edit:
I found this page as well,with lots of great info/pics on contrails/aviation smog:
Aviation-smog, caused by air traffic at great heights may have undesirable consequences for weather, climate and the quality and quantity of the Sun's radiation that reaches the surface of Earth. In the discussion about radiative forcing, greenhouse effect and global warming, this deserves more attention.
—Contrails and Aviation Cirrus In just a few hours a contrail that begins life only a few meters in width can spread to cover more than 20,000 square kilometers. —NASA Langley Cloud and Radiation Research Center
In 2000 there were 8,951,773 commercial aircraft departures in the United States alone.—AirTraffic
"Some unburned fuel is found in jet-aircraft exhaust" "Most petroleum fuels are mixtures of hundreds of different hydrocarbon compounds"
"It seems sunlight is mimicking the conditions in the combustion chamber which activate the lead chemistry"
