Yes, 54 Squadron is a good shout, as is 66 Squadron which arrived in Flanders in time for bloody April, 1 RNAS and 8 RNAS were both helping the RFC out at that time.

April 1917 is too early for Camels but 54 and 66 will be flying Pups and the RNAS squadrons should be Triplanes or maybe Pups for the lesser ranks.

By the summer of 1917 the sky over Flanders should be really filling up with the Camels appearing in the Autumn. 70 Squadron changed to Camels at that time I know.

"A great deal of an aeroplane could be holed without affecting its ability to fly. Wings and fuselage could be—and often were—pierced in 50 places, missing the occupants by inches (blissfully unaware of how close it had come until they returned to base). Then the sailmaker would carefully cover each hole with a square inch of Irish linen frayed at the edges and with a brushful of dope make our aircraft 'serviceable' again within an hour."
