Regrading the jet fumes, yeah if you're within 3-5 miles of a major airport, there's definitely jet fumes drifting around. Source: Helped someone one weekend re-roof their house that was probably 3 miles from Logan Airport in Boston. You'd get waves of fumes slowly drifting down from the big heavy jets taking off one after another after another.
