As one who flies around 200 hours a year, and hasn’t burned a drop of avgas in 18 years, (I fly a Rotax, which actually prefers mogas) I am somewhat out of the picture, BUT, I am somewhat surprised it’s taken this long for these kinds of BS lawsuits about “spewing lead” to raise their head. To be clear, I’m on the lead spewing side! As in, not enough to matter or quantify, but it does seem like an easy target for the enviro wackos.
