First became interested in aviation whilst working at the Empress Motor Works, Manchester a year later he went to Brooklands to be a mechanic for the French pilot, Maurice Ducrocq. In 1914 joined the Royal Naval Air Service as an instructor, having held a flying certificate for two years. In 1916 he was posted to the Middle East, where he was a member of the Number 2 wing in the Eastern Mediterranean. Operating out of the base in Mudros, Alcock made many daring bombing raids. He nearly lost his life in 1917 when his plane experienced engine failure and he and his crew were forced to ditch their plane at sea. When they swam ashore, they were taken prisoners by the Turks. After the armistice, he was released, and he left the Royal Air Force in March of 1919. On June 14, 1919, Alcock, along with his navigator, Lieutenant Arthur Whitten Brown, left St. John's, Newfoundland and flew across the Atlantic, a distance of 1,960 miles to Clifden, Ireland in 15 hours and 57 minutes. For this record-breaking flight he was created Knight Commander Order of the British Empire, by George V at Buckingham Palace on June 21, 1919. On December 18, 1919, Sir John Alcock, KBE, DSC, flew to Paris to exhibit a Vickers Viking amphibian aircraft. On his landing at Cote d'Evrard he sustained a skull fracture. He was taken to a hospital in Rouen, but he never regained consciousness and he died that very same day.

Born 23 July 1886 in Glasgow, but educated in Manchester. Brown served an apprenticeship with the British Westinghouse Electric and Manufacturing Company (later Metropolitan-Vickers Electrical Company Ltd) at Trafford Park, Manchester. In January 1915 he gained a commission in the Manchester regiment and took part in the second battle of Ypres before being transferred to the Royal Flying Corps and trained as an observer. In November 1915 he permanently injured one leg when he was shot down over Valenciennes in France. He remained a prisoner of war of the Germans until he was repatriated in September 1917. He then worked in the aircraft production department of the Ministry of Munitions until the end of the war. In 1919 Brown, visited Vickers of Weybridge seeking a post, shortly after the firm had decided to make an attempt on the first direct flight across the Atlantic for the prize of £10,000 offered by the Daily Mail. Brown was offered the position of navigator, alongside John Alcock as pilot. After the flight, Brown returned to work for Vickers Ltd and then again for Metropolitan-Vickers. During the Second World War he returned to the Royal Air Force in order to train pilots in navigation and engineering, though he never flew again after Alcock's death in 1919. He died at his home in Swansea on 4 October 1948 from an accidental overdose of veronal. A memorial to Alcock and Whitten Brown was erected in 1952, near the field from which they took off at St John's, by the Historic Sites and Monuments Board of Canada. A memorial by William McMillan was erected at London Heathrow airport.

Steel makers, armaments and engineering manufacturers founded in Sheffield in 1828 by the miller Edward Vickers and his father-in-law George Naylor. In 1863 the company moved to a new site in Sheffield on the River Don in Brightside. The company went public in 1867 as Vickers, Sons & Company and gradually acquired more businesses. In 1911, the company name was changed to Vickers Ltd. The company expanded into aircraft manufacture with the formation of Vickers Ltd (Aviation Department). In 1927, Vickers merged their armaments, shipbuilding and heavy engineering activities with Armstrong Whitworth to form Vickers-Armstrong Limited.
