When Furious was at Scapa, her aircraft squadron, commanded by Dunning was sent to Smoogro, from where the aircraft, a handful of Pups would fly alongside the carrier's deck. Geoffrey Moore in his book Early Birds discusses the timing. It was in his aeroplane that Dunning lost his life; Dunning's had suffered damage during his second landing and was undergoing repair. Sadly, Dunning's life was cruelly taken by fate and the unreliable technology of the day, rather than the dangers of what he was doing; he approached the carrier too high and realising his mistake attempted to restart the engine (being a rotary, the Pup's motor had blip switches rather than a throttle), but it didn't start and the aircraft went over the side. Dunning drowned before they could get to him.
After this incident, landing on Furious was banned, although Dunning's replacement, Sqn Cdr Fredrick Rutland (Rutland of Jutland) carried out a touch and go without landing on the deck to satisfy himself that he could do it. These guys had balls of steel. Hats off to them.
