Praise and astonishment from “aviation enthusiasts”? They must be young enthusiasts since this type of ferry flight has been taking place for at least a decade now.
Not necessarily. Just because it wasn’t the first time it was accomplished, doesn’t diminish the risk, deprivation, and courage necessary to complete such a flight. Everything’s nominal, until it isn’t. Look at the crew still stuck on the Space Station. My only question is if “every inch of the aircraft’s interior was fitted with a fuel cell”, where did he stow his ditching gear, wing lockers?
For myself, the maximum range of my C172 is limited primarily by my wife’s bladder.
Meh… A friend of mine did this in the 70s & 80s before GPS and magenta lines made it more of an mental endurance event than an aeronautical challenge.
