Adrian "Warby" Warburton, DSO* DFC** (10 March 1918 – 12 April 1944) was a Royal Air Force (RAF) pilot and flying ace of the Second World War.In April 1940, 22 Squadron moved to RAF North Coates in Lincolnshire and was involved in mine-laying operations, night bombing of enemy ports and, in May, daylight raids to try and stem the tide of the German Blitzkrieg.Australian Flight Lieutenant "Tich" Whiteley had been tasked with delivering three American-built Martin Maryland aircraft to Malta to be used for reconnaissance.This was witnessed by an irate wing commander, and Tich was firmly reprimanded for risking a precious aircraft in the hands of such a "ham-fisted idiot"."[5] Two days later, during combat with another seaplane and three Italian fighters, a bullet hit Warburton's instrument panel before penetrating his harness and striking him in the chest.431 Flight was sent to Malta following pressure from the Commander-in-Chief (C-in-C) Mediterranean, Admiral Cunningham, who wanted "eyes" on the powerful and modern Italian battle fleet.These were crucial: "An aircraft from Illustrious working from Malta then picked up full details of the enemy’s dispositions, together with photographs showing the anti-torpedo nets and barrage balloons, and it was in the light of these that the Swordfish crews planned their attack.Years later, Spires said Warburton told him they were going in at zero feet, and he was to get a sharp pencil and plenty of paper to plot the ships on the harbour map.Cunningham's despatch on the operation, published in 1947, said the success of the Fleet Air Arm attack was due in no small part to the excellent reconnaissances carried out by 431 Flight, under very difficult conditions and often in the face of fighter opposition.Later the same month, the citation for Warburton's Distinguished Flying Cross (DFC) was published in The London Gazette: This officer has carried out numerous long distance reconnaissance flights and has taken part in eight air combats.But the American Maryland, built primarily as a light bomber, had forward- and rear-facing guns, enabling Warburton and his crew's success in air combat.Warburton's attire became an expression of his individuality and he often wore an army battledress blouse with his RAF rank on slides on the shoulder tabs.Many were jealous of Warburton's access to senior officers, and in particular the new AOC, Air Vice-Marshal Hugh Lloyd, who gave him free rein.When 2 PRU acquired two Beaufighters, its commander, Squadron Leader Hugh McPhail, had them stripped of guns, cannon, and other equipment, to increase their speed and ceiling.Within 24 hours, he was revisiting his old haunts including Tripoli, all of Sicily, and southern Italy, once again under the direct control of Air Vice-Marshal Hugh Lloyd.On 13 February 1942, he conducted a reconnaissance of Taranto accompanied by Corporal Ron Hadden, who said it took them two attempts to penetrate the harbour because of low cloud.Warburton was sitting calmly, with a cigarette stuck in the corner of his mouth, his elbows propped up on the sides of the cockpit, and with his beloved service cap pulled over his flying helmet.The two camera operators, Corporal Ron Hadden and Leading Aircraftman Norman Shirley were each awarded DFMs, making them unique, as they were not aircrew.Warburton force landed, then walked out, earning the unofficial "flying boot" emblem, which he wore on his left breast pocket.Under the new AOC, Air Vice-Marshal Keith Park, 69 Squadron expanded into three flights, each operating a different type of aircraft: the Baltimore, Spitfire, and Wellington.Having made his way to Gibraltar, Warburton borrowed a Spitfire fighter to fly back to Bône to pick up his undamaged camera magazine.Hugh O'Neil flew the fighter escort and commented that Warburton was undeterred by the flak, simply smoking a large cigar as he went about his task.Canadian Bill Carr from 683 Squadron described what Warburton then did: Growing tired of being bed-ridden, he climbed out of the window, "borrowed" a vehicle, and made his way to the airport.The aircraft separated approximately 100 miles (160 km) north of Munich to carry out their respective tasks; it was planned that they would meet before heading south.Although he rented a bungalow near Thorney Island where he was based, he virtually ignored his new wife, visited rarely, and lived in the officers' mess, as required by RAF regulations.George Lawson, who commanded the 7th PRG and reluctantly authorised Warburton's last sortie said, "Warby told me he was going to San Severo in Italy and had no intention of going to Sardinia."[19] Christina's story was featured in the short musical play Star of Strait Street, by Philip Glassborow, which opened in Valletta in 2017, and she is the central character in the book Ladies of Lascaris, by Paul McDonald, published in 2018.Years of speculation about Warburton's fate came to an end in 2002, when his remains were found with his aircraft, buried about 2 yards (1.8 m) deep in a field near the Bavarian village of Egling an der Paar, 34 miles (55 km) west of Munich.Rumours persisted locally that the remains were buried in a grave at St Johannes Baptist Church in Kaufering, which already contained seven airmen from an RAF Halifax shot down the previous year.Warburton was the subject of the "Mystery of the Missing Ace" episode of the BBC investigative documentary series Timewatch, first broadcast in November 2003.
