Who was the major league baseball player that retired young because he was afraid to fly?

Answer 1

This answer is strictly from memory but I am virtually certain that Jackie Jensen was reputed to have quit playing for the Boston Red Sox because he was afraid to fly. He originally broke in with the NY Yankees coming up the same year and from the same Pacific Coast team as Billy Martin. Also believe Casey Stengel was their minor league manager who was promoted to the Yankees in the same year. Note also that Jensen was a very good College Football player (halfback?) on the West Coast and believe he played in the Rose Bowl one year.
