Just in case anyone is interested, but it seems that the flyers mentioned in the above post have been identified.
They were possibly Vfw. Rudolf Mischke (pilot) of Reichenbach and Ltn.d.R. Herbert Reissig (observer) of Berlin. They flew with FA 263. The aeroplane was an Albatros (D type).
Would anyone be able to conform that FA 263 flew these?
They were possibly shot down by Ltns. H.W. Sellars and C. C. Robson of No. 11 Squadron.
