LOCAL OFFICER’S DEATH
News has been received that Lieut. [sic] John Gibson, of the Royal Flying Corps, was killed whilst on active service on the 19th inst. He was commencing a flight, and on leaving the ground his machine collided with a hay mower. The impact was so great that the aeroplane was completely smashed. Lieut. Gibson received injuries from which he died almost immediately, but the observer, who occupied the front seat, had a miraculous escape, sustaining only a few bruises. Immediately on the outbreak of war Lieut. Gibson joined the 2nd Devon Cyclist Corps (T.F.) and subsequently obtained a commission in the Motor Transport but, being very anxious to get out to France, he transferred to the Royal Flying Corps. He was 28 years of age, and the only son of the late Mr George Frederick Gibson, of Newcastle. He was a grandson of [the] late Mr and Mrs Donkin of Haw Hill, Rothbury, he being the only son of their daughter (Mrs Gibson), who died some years ago.
He is remembered at Benwell on B86.02
