The FBO fuel sales model is broken and anti-competitive

In almost every article about the future of leaded avgas, this statement appears, “… only one fuel will be stocked by the FBO system.” This particular quote comes from a reply by Mac McClellen to Todd Petersen in Mac’s latest Left Seat blog on the EAA’s website. You will also find it in almost every article and editorial from any aviation alphabet organization about the modern state of 100LL avgas.
