> my main thought here is that we should not continue to manufacture engines that burn leaded fuel. I don't disagree with you, but there are many thousands of perfectly good planes from previous decades that are in good shape (they have to be inspected annually) that will be a long legacy. Right now I can find 63 pre-1960 single-piston aircraft for sale, with the cheapest being US$ 42K from 1945 as I type this: * https://www.controller.com/listings/search?Category=6&ScopeCategoryIDs=13&Year=1928%2A1959&sort=2 https://www.controller.com/listings/search?Category=6&ScopeC... One of the oldest is a 1928 biplane ($130K). If you're a WW2 enthusiast there's a 1940 Hawker Hurricane for US$ 2.7M.
