Watching the Dallas Cowboys perform, it is not difficult to believe that coach Tom Landry flew fourengines bombers during World War II. He was in B17 Flying Fortresses out of England, they say. His cautious, conservative approach to every situation and the complexity of the plays he sends in do seem to reflect the philosophy of a pilot trained to doggedly press on according to plans laid down before takeoff. I sometimes wonder how the Cowboys would have fared all this years had Tom flown fighters in combat situations which dictated continuously changing tactics.
