Wait until you find out that jet planes use leaded fuel.

Relevant bits:

Avgas is a specialized fuel used to power piston engine aircraft.

Jet aircraft and turbine-powered, propeller aircraft do not use avgas, but instead use fuels very similar to kerosene, which does not contain a lead additive.
