Well...powering heavier-than-air flying machines by burning dead dinosaurs is about as unnatural as it gets. Civilization and all that ;) Edit: someone seems to think that unnatural = wrong? On the Internet - a place that is so un-natural that it doesn't even physically exist? What irony.

Some planes still use leaded fuel which presumably fall closest to the ground in poorer parts of the country because in many cities airports are built where land is cheapest. Certainly not the same as chemtrails but I have wondered what kind of health effects come as a result.

  Children living close to the airport serving leaded avgas were found to have a small but tangible increase in blood lead levels. General aviation itself has been on the decline for the past few decades and alternative fuel seems to be finally getting approved at last, so the problem seems to be a well managed one. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3230438/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3230438/
