Thanks Drew, just trying to put whatever pieces I can together. It's a long time ago and my father died without passing on much in the way of real detail about my grandfather's flying career in 1917/18. My aunt (83 now) survives and has a lot of anecdotal stories but they're not facts until I can verify them.
My grandfather was, he himself admitted, luckier than many better men as he survived the war. He thought himself incredibly fortunate to be a pilot and always mentioned his pity for the 'Poor Bloody infantry'. He was troubled by a long running depression which he tried very hard to keep in check. I sometimes wonder if he was carrying some guilt for actually having survived.....

Best, Tom
