That was an interim state. It is now approved for all type-certificated spark-ignition piston engines.

I stand (sit) corrected.
Lack of options should never have prevented lead being outlawed. Ask anyone on the street "Would you like to drink this potion making you dumber so that someone else can fly a plane up there" and everyone will say no.

Clearly it isn't okay to harm someone without their knowledge or consent.

I'm an airplane owner, and I agree. If they had outlawed it, I bet the solution would have come a lot faster.
Where exactly do you think your airline pilots come from? You know, the ones there is a giant shortage of right now… Do you think they grow on trees? They learn to fly in those small piston planes.
Overwhelmingly the Air Force
lol not even close in USA...
