I thought that it was a bit long, but the conclusion was most persuasive, especially as Bader was in POW camp with the guilty party (and probably worked out the truth for himself!).
What puzzles me still:
(1) the revelation that the Germans only lost one aircraft that day (which was well identified as done by someone else), so surely if it had been a collision, there would have been two? Why did no-one realise this earlier?
(2) Bader also claimed one destroyed that day (and the one that hit him as a probable!) which looks like a total invention, which was not even mentioned!
