Correct me if I am wrong, but I think the one eyed Hunter pilot became a navigator. At the time of me losing the sight of one eye (1983) there were no pilots with one eye. I was the first at that date & then only able to fly 'as or with co-pilot'. Later, having flown royalty & heads of state as captain I persuaded their airships to let me fly solo & as a full FI. Sadly I never flew the VC10 solo.
