Anyone curious how the RFC ranged artillery during WW I might want to go to the great war forum invasioonzone19141918.com war in the air section posting deciphering ranging in artillery report 2 Squadron which tells how it was done. on theaerodrom.com forum other WW I aviation section there are posts of RFC communiques from 100 years ago that day which has the RFC mainly spotting RGA Siege batteries and on a few time RMA 15 inch howitzers on the Germans sometimes very effectively.
