What about the pilots? I always get this fuel on my hands during preflight when sumping the fuel tanks.

  Lead doesn't absorb through the skin. You have to breathe or eat it. As long as you thoroughly wash your hands after preflight, the only exposure should be the fumes and exhaust in the air.

    No, tetraethyl lead, which is the form of lead found in fuel, is easily absorbed through the skin.

  Maybe pilots should be required to lick a block of lead before each flight, so they have some incentive to stop using leaded fuel.

    Without a legal replacement fuel (which is now in the works, but still not generally available nor legally approved for most aircraft), incentive isn't enough.

    With almost no exceptions, pilots have exactly zero say in what fuel to use. Airplanes are certified to use certain fuels and that's what you have to use. At this point there is no generally approved unleaded replacement for 100-octane avgas (although several are in testing.) A few engines, mostly low performance ones, have the option to use automobile gas, but even in those cases it's rarely available at airports so it's not really an option either.

      They own the plane. They choose the engine. They choose to fly. They choose to lobby against engine upgrades. They choose to poison us.

      Many of these pilots are basically just rich people flying for fun.
