Documentary on TV a month or so ago about a team that went hunting for the wreck of Bader's Spitfire to prove how he finally came to earth. Having read both British and German after action reports for that day, they came to the conclusion that Bader was the victim of a "Blue on Blue" and he claimed to have had the collision to avoid the embarrasment of being where he was not supposed to be!
One wonders how deliberate it was.......
