Jets do (as well as turboprops), but piston-engine planes (aka almost all general aviation aircraft) currently burn leaded gasoline.

  Jets and turboprops do not use "unleaded fuel", they use jet fuel (which is basically kerosene). "Unleaded fuel" doesn't mean any fuel without lead, it specifically means gasoline (petrol) without lead. Hydrogen gas (or liquid) can be used as a fuel, but no one would call it "unleaded fuel".

      Yeah, that one is exactly like all the "gluten free!" stuff being marketed, which never had gluten in the first place.
