The captain that successfully dead-sticked the TACA 737 on a levee after a dual engine power loss only had one eye (IIRC he lost it when he got shot in the head while flying an evacuation during a civil war).
I suspect a high percentage of commercial airline pilots - without any sort of physical handicap - could not have done as well
Personally I'll take a highly skilled pilot with a physical disability over a physically sound mediocre pilot.
