Not written well.
Longish story but flew a PT6 engined twin over 400 miles back home once - over water the whole way - on lubed up AvGas.
Ran a bit hot but was fine!
Though I was running a tiny bit. Much trust for Messrs Pratt and Whitney but wasn't 100% on the quality of the AvGas!!
I've seen a vid of the big GE running on water! 5 ton of water a minute flowing through it??!!
