Yes, I've read his book, and heard the bad press that he was subject to. It's difficult to know what to think, after all, both Bader and Gibson were not popular with everyone. Clostermann seemed to manage to annoy those who flew with him, whereas Bader at least seemed to have the loyalty of those on his Sqn / Wing, if not elsewhere.
Still, it was a remarkable story for the Frenchman, and I think that I will at least do him the honour of reading The Big Show once more.
