No worries about my previous post. A case of cross-purposes really. Accuracy wasn't my theme. 1917 clearly went to great lengths here but the whole didn't gel with me. I can't see myself wanting to view it again, unlike many others. After seeing Journey's End I bought the DVD and have watched it at least half a dozen times - even got a copy of the play and the book about the 9/East Surrey Regt. My other top war/military films (regardless of any "accuracy" issues) are Thin Red Line, The Cruel Sea, The Enemy Below, Das Boot, Atonement, Life & Time of Colonel Blimp, Colonel Redl, and Tunes of Glory. The last is a gem of a film, and I can have teary eyes at the ending even after seeing it many times.
Back to WW1 aviation, here is a thought: as 1917 was set during "Bloody April" perhaps poor young Blake should have been killed by the crash of a shot-down RFC plane, perhaps a DH2 or BE2c struggling back to the British lines - or even by the Albatros coming in a for a coup of grace strafe?
