Did the magnificent John Farley fly the F-35B? He flew the VAAC Harrier version? Anyhoo this is how it goes ashore. Complexity is the job of the computer flight controls while the pilot positions the F-35B accurately according to F-35B pilot reports with failure modes in STOVL flight also taken into account but what caused the accident under discussion - I have no idea.
