 The Sopwith aircraft was the lightest and highest-powered aircraft in service with the Royal Naval Air Service, and the close call in a favourable wind demonstrated that heavier aircraft could not be launched from the flight deck.By October 1915 "Campania" had exercised with the Grand Fleet seven times, but had only flown off aircraft three times as the North Sea was often too rough for her seaplanes to use.Her captain recommended that the flying-off deck be lengthened and given a steeper slope to allow gravity to boost the aircraft's acceleration and the ship was accordingly modified at Cammell Laird between November 1915 and early April 1916.
