timber-framed house, is considered the city's most important historic building and re-opened after renovations in summer 2011. Flying boats and seaplanes Flying Boats operated passenger and mail service from Southampton between 1919 and 1958. At that time, runways suitable for large aircraft were scarce and aeroplane engines less reliable; in the event of engine trouble, passengers and crew were safer over water in a marine hull than a craft with wheels and a lightweight frame. The first service in 1919 flew from the Royal Pier to Bournemouth and the Isle of Wight. During the 1920s, flights operated from Woolston to Northern France. Aircraft technology improved, and in 1937 Imperial Airways began service to East and South Africa and the United States. There was later additional service to destinations including Australia, Tokyo, Karachi, Singapore and Hong Kong. In 1937 aircraft were maintained at the Hythe flying-boat base; the terminal was at Berth 101, in the western docks. In 1938, passenger operations were conducted from Berth 108 in the new docks. In September 1939, aircraft and services were transferred to Poole Harbour under the direction of National Air Communications by BOAC (evolving from the merger of Imperial Airways and British Airways Ltd). Post-war service operated from Berth 50 in the old docks. In 1950 BOAC ceased its flying-boat operations, but Aquila Airways continued service until 1958. A Short Sandringham flying boat is on display at Solent Sky. The Supermarine works in Woolston was known for its success in the Schneider Trophy races, especially its three consecutive wins in 1927, 1929 and 1931. From his experiences with seaplanes Reginald J. Mitchell became chief designer of the Supermarine Spitfire fighter, which played a prominent role in World War II. A Spitfire and a Supermarine S.6A are also on exhibit at Solent Sky. Military Southampton Southampton has a history as a departure point for soldiers dating to Henry V's departure for Agincourt in 1415. It has been heavily involved in most of the wars Britain has fought. It was the point of departure for troops heading for the Crimea and the British Expeditionary Forces heading for France in both World Wars. It was also the major port of embarkation for troops and materiel involved in Operation Overlord in 1944. The Marchwood Military Port, built in 1943, is the base for the 17 Port and Maritime Regiment of the Royal Logistic Corps and home port for
