Born on 7 January 1918 in Christchurch, Antonio Simmons Dini was one of seven children of Pietro Antonio Dini and his wife Minnie née Moorhouse.^[1][2] Of Corsican descent, he was educated at Christchurch Technical College after which he found employment at the Post & Telegraph Department.^[1]

Dini made a successful application to join the Royal Air Force (RAF) on a short service commission with the serial number 40609, leaving for England in December 1937. Dini started flight training early the following year at the de Havilland flying school at Hatfield Aerodrome, proceeded to the RAF station at Uxbridge, and then on to No. 3 Flying Training School at South Cerney.^[1][3]

After gaining his wings, Dini was loaned to the Fleet Air Arm, the aviation branch of the Royal Navy, in October 1938. Assigned to the RAF's School of Naval Co-operation operating from Ford in Sussex, he flew Supermarine Walrus amphibious aircraft.^[1][3] His rank of pilot officer was confirmed early the following year.^[4] When the school was reorganised on 24 May 1939, Dini was posted to 751 Naval Air Squadron. Just over a week later, he was involved in a fatal incident when, as the pilot of a Walrus, he crashed the aircraft into the sea off Littlehampton. He was the only survivor of the three-man crew and, being concussed, had no recollection of the crash, with its cause being unable to be determined.^[3][5][6]

By the time of Dini's return to active duty after recovering from the injuries arising from his crash, the Second World War had broken out. On 4 September, he was posted to No. 66 Squadron, which flew Supermarine Spitfire fighters from Duxford. From here it was occasionally scrambled to intercept incoming German aircraft and also carried out patrols over the North Sea.^[3][7] On 1 May 1940, Dini was posted to No. 607 Squadron, which had been sent to France the previous November as part of the Air Component of the British Expeditionary Force. At the time, the squadron, equipped with Hawker Hurricane fighters, was based at Vitry-en-Artois, near Arras.^[8]

Battle of France edit

No. 607 Squadron saw little activity for much of its time in France.^[9] However, once the Battle of France commenced on 10 May, Dini was promptly in action. At around 4:15 am, he and two other pilots from his squadron engaged Heinkel He 111 medium bombers that were attacking the airfield at Vitry. He damaged one of the bombers. Dini made three more sorties that day; in the afternoon, he shared in the destruction of a He 111, had sole credit for another shot down He 111 and on his last flight of the day, damaged yet another He 111.^[8][10]

Dini helped shoot down another He 111 on 11 May northeast of Brussels and then two days later destroyed a Messerschmitt Bf 109 fighter close to Diest. He engaged and claimed to have shot down a Dornier Do 17 medium bomber on 16 May, although this could not be conclusively confirmed. The next day, Vitry was raided again and Dini's Hurricane was damaged during the attack, forcing his return to the airfield. Despite this, later in the day he destroyed a Do 17 bomber east of Cambrai and then shot down two He 111s near Binche, in Belgium. He may have shot down another two Do 17s the following day, but this was unable to be verified.^[10][11]

By 22 May, No. 607 Squadron had been withdrawn to England and was reassembling at Croydon.^[9] However, on his return to England, Dini was posted to No. 605 Squadron, another Hurricane-equipped unit and based at Hawkinge at the time but about to move to Scotland, where it was to operate from Drem. On 31 May he was killed when he crashed near Folkestone soon after taking off in his Hurricane for the flight to Scotland. He had experienced an engine failure and his aircraft rolled into a dive.^[11][12] He is buried at Hawkinge Cemetery in Kent.^[2][13]

According to aviation historians Christopher Shores and Clive Williams, Dini is credited with destroying five enemy aircraft, and shared in the destruction of two more, two damaged, and three inconclusive.^[10]
