Narrative:
24.3.17: Sopwith Triplane N5473, RNAS Dunkerque. Written off (destroyed) due to structural failure in flight, when broke up in dive out of cloud (reportedly, a wing broke off) near Fort Burgoyne, RNAS Dover, Kent. Pilot - Flt Sub-Lt William Smith Oliver (Canadian, aged 25) - was killed.

According to a contemporary report in "Flight" magazine (March 29, 1917 page 292 - see link #4)

"At the inquest on March 26th on Flight-Lieut. W. S. Oliver, who was killed whilst flying in Kent, it was stated that the machine fell about 2,500 ft., and that when it emerged from a cloud it was nose-diving. The wings on one side appeared to fall away, and the aeroplane crashed to earth. A verdict of "Death by Misadventure" was returned"

According to one published source (see link #6)

"Dover-based Triplane N5473 breaks up in a dive from 2,500ft killing the Canadian pilot. This restarts rumours about the strength of Sopwith ‘Triplanes’ which have been through ‘factor of safety’ structural tests at Farnborough including a test to measure the bending load required to break the fragile looking fuselage structure
