The faster we get tetra ethyl lead out of aviation fuels, the better. This moronic glorification of leaded gas is just stupid.
The good old days of leaded fuel and cars? Yeah, like the good old days we made soldiers watch nuclear explosions, exposing them to radiation.
Everyone bitched and moaned when taking it out of car fuel years ago. Now cars have far more power than they ever did.
Figure it out. If it takes billions to transform the relatively few airplanes that can’t legitimately run on unleaded, then trade them in and replace them by government subsidy.
