It would be more of a triumph if those $30 flights were not using leaded fuel, or if there was at least some lead pollution task to encourage people to take different transit options until the airline industry figures it out. I think, it was much less of a problem, when many less planes were flying. -- Correction in the comment, Jet-A has no lead. Cursory research suggests its nasty products are mostly organics rather than heavy metals, which is much less bad.
