The unshown part of this story is that it is now thought that despite his books and documentaries and the film Reach For The Sky showing, or talking of him colliding with Grman fighters or being shot down by a German Sgt pilot, in fact he was the victim of a mistaken friendly-fire incident whereby his friend and fellow wing pilot Buck Casson shot him down as he was lose behind a pack of German fighters and Buck was possibly closing fast on this rear aircraft, posssibly shooting towards the brighter part of the sky where the sun was startling at higher altitudes. If you read Bader`s Last Fight or other books this is now becoming apparent. It still was a remarkable escape from the Spitfire and we have the legend of Bader doing the work most able bodied could not do. Love him or hate him, you had to admire his guts and his work for charity and as an inspiration for thousands of limbless children and others who now had an example of what is possible with no legs;to fly, to drive, to dance with the Queen Mother, to play Golf better than some pros and to leave us a legend of courage in the skies defending Britain in 1940. There will never be another.
