Ward was a 22-year-old sergeant pilot with No. 75 (NZ) Squadron when he carried out the action for which he was awarded the Victoria Cross (VC). He was co-pilot on a Vickers Wellington bomber flying out of RAF Feltwell in Norfolk, United Kingdom. On 7 July 1941 after an attack on Münster, Germany, the Wellington (AA-R) in which Sergeant Ward was second pilot was attacked by a German Bf 110 night fighter. The attack opened a fuel tank in the starboard wing and caused a fire at the rear of the starboard engine.Vickers Wellington L7818 'AA-R', pictured on return from operations on 7 July 1941. Shown are the holes Sgt Ward made to help him climb across the wingThe skipper of the aircraft told him to try to put out the fire. Sergeant Ward crawled out through the narrow astrodome (used for celestial navigation) on the end of a rope initially reported as being taken from the aircraft's emergency dinghy, but actually from an engine cover. He kicked or tore holes in the aircraft's fabric with a fire axe to give himself hand- and foot-holes. By this means he reached the engine and attempted to smother the flames with a canvas cover.Although the fuel continued to leak, with the fire out the plane was now safe. His crawl back over the wing, in which he had previously torn holes, was more dangerous than the outward journey but he managed with the help of the aircraft's navigator. Instead of the crew having to bail out, the aircraft made an emergency landing at Newmarket, United Kingdom.
