This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Little known fact. Airplanes still use leaded fuel. I’ll bet that the blood levels for all of these families are elevated. Not a great place to raise a kid.
Clarification: Only piston aircraft require leaded fuel. Which is unfortunately a pretty big part of the general aviation market, but similarly sized turboprops do also exist (though are more expensive) and it doesn't apply to modern commercial aviation at all.
Further clarification: Only gasoline powered aircraft without the Auto Fuel STC require leaded fuel.
Although, there is an initiative underway to fully phase out leaded avgas. G100UL is the FAA approved formulation. Exciting time and long overdue.
There are also some plans in the works to fully end leaded avgas in the 2030s.
Disgusting.
