Sean flew with roughly 60 different men at various times . At the end of WW2 only he and  9 others were still alive .

Staying alive until 45

      Why did he survive when so many others died ?   The biggest reason  is probably luck . One more reason might be his habit of coming home at 12,000 ft (4,000  meters ). The rest of the bombers were up around 20,000 ft  (7,000 meters) and he guessed, so were the night fighters .

       Why did Sean manage to stay alive when so many others died ?  The odds against aircrew in the early years ,1940 to 1943 , were staggering. A man had about a 1 in 30 chance of completing one tour. (thirty  missions or as they called them back then, operations ). The odds against completing two tours was 1 in 40.
