Posting because I saw another post on this community about Extinction Rebellion UK blocking a private jet airport today (June 2024) (https://extinctionrebellion.uk/2024/06/02/climate-activists-blockade-farnborough-private-jet-airports-three-main-gates/) and wondered how many people know that leaded fuel is still pretty common in planes, both in the UK and elsewhere; I was pretty shocked when I first learned this
Leaded fuel is still used in piston airplanes everywhere. While there are ongoing efforts to develop an unleaded alternative, there is none currently available to the market.
