Kallang Airport

The Kallang Airport also known as the Kallang Aerodrome, Kallang Airfield and RAF Kallang, opened in 1937 as Singapore's first purpose-built civil airport, together with an anchorage for seaplanes. Land was reclaimed in the Kallang Basin to turn the swampy area into a circular-shaped airfield and to build a slipway for the seaplanes. The airport was closed in 1955 when the new Singapore International Airport at Paya Lebar was built. Although most of the airport was demolished and put to other use, the distinctive terminal building was used as the headquarters of the People's Association until April 2009. It is currently unoccupied.

History
Singapore's strategic location on the routes from Europe to the Far East, Australia, New Zealand and the Pacific Islands, traversing the Middle East and India, made it an ideal centre to serve the region in aviation. In 1930, the RAF-owned Seletar Airbase was opened to commercial aircraft.

On 11 February 1930, the Dutch Airline Koninklijke Luchtvaart Maatschappij (KLM) operated the first service flight between Amsterdam and Batavia (since renamed Jakarta), landing in Seletar with a Dutch-made Fokker trimotor monoplane carrying 8 passengers and a cargo of fresh fruit, flowers and mail. This marked the beginning of commercial civil aviation in Singapore. KLM later introduced a regular Amsterdam to Batavia flight service in late-1931.

Two years later, in July 1933, Imperial Airways, the flagship airline of the British empire at the time, started a service between London and Darwin via Cairo, Karachi, Calcutta, Singapore and Jakarta. This service was later extended to Brisbane and operated jointly with Qantas Empire Airways on 17 December 1934.

Booming commercial aviation traffic led to congestion at the existing Seletar Airbase (today's Seletar Airport), creating a need for a new airport. On August 31, 1931, Sir Cecil Clementi, then Governor of the Straits Settlements, announced that Kallang Basin would be the location for the new civil aerodrome suitable for land planes and seaplanes, and relieving Seletar of commercial flight activities.

Construction
Reclamation work began on the 103 hectares of tidal swamp in Kallang Basin in 1932. Seven million cubic metres of earth were used for the filling of this tidal swamp. By 1936, all reclamation and consolidation of land were completed, forming a 915-metre diameter, dome-shaped landing ground.

On 12 June 1937, the Kallang Aerodrome was officially opened by Sir Shenton Thomas, who had taken over the governorship of the Straits Settlements from Sir Cecil in 1934. At the time it was hailed as "the finest airport in the British Empire", with facilities that were considered revolutionary. The circular aerodrome allowed planes to land from any direction, and the slipway allowed seaplanes to be served at the same terminal building as regular planes. The terminal building itself was considered a marvel, with a large open-air viewing gallery on the top of the two-storey building and a circular control tower in the middle of the glass-covered building.

World War II
When the Japanese launched their invasion of Malaya and Singapore on 8 December 1941, Kallang was the principal fighter airfield. By January 1942, it was the only operational fighter airfield in Singapore, as the other airfields (Tengah, Seletar and Sembawang) were within range of Japanese artillery at Johore Bahru.

Brewster Buffalo fighters of 243 Squadron RAF, 488 Squadron RNZAF and a detachment of 2-VLG-V of the Royal Netherlands East Indies Air Force operated from the airfield, defending Singapore from repeated Japanese air raids. They were joined later by Hawker Hurricanes of 232 Squadron RAF, but attrition took a steady toll on men and machines, and by the last days of January 1942, the airfield had been badly damaged by the bombing and only a small number of aircraft were serviceable. The last of the fighters left in early February, escaping to carry on the fight just before Singapore was surrendered to the advancing Japanese.

The war years and after
The growth in aviation traffic was stunted during the war years, a period which saw the landing circle being converted into a single runway to allow use by warplanes. The British Overseas Airways Corporation (BOAC) and Qantas resumed their regular services to the airport, while the resurrected local airline Malayan Airways (MAL) began services on 1 May 1947.

In the early 1950s, the increasing size of airplanes and the need for longer runways resulted in it being extended beyond Mountbatten Road in the eastern boundary of the facility into what is now Old Airport Road. This necessitated the installation of traffic lights to halt vehicular traffic every time a plane took off or landed.

Closure
The success of Malayan Airways and rapid growth again caused congestion at the facility, while advancing technology necessitated extension of the only runway. This was no longer possible because of residential areas in the way, leading to a decision to build a new facility at Paya Lebar in 1951, 8 km further from the city. When the new airport was completed on 20 August 1955, Kallang Airport was closed down, and all associated facilities moved to the new facility. The runway was converted into a road, and the airfield turned into a recreational area with the building of the National Stadium and Singapore Indoor Stadium.

Accidents and incidents

 * On 29 Jun 1946, one of the Dakota aircraft belonging to the Royal Air Force Police with 20 NCOs on board crashed at the Airport in a storm with no survivors. The nearby road Dakota Crescent and the subway station Dakota Station are named in commemoration of this disaster.
 * On January 10, 1954, BOAC Flight 781, originating from Kallang, took off from Rome for its final leg to London and broke into pieces in mid-air. This led to an investigation into the airworthiness of the de Havilland Comet airplanes.
 * On 13 March 1954, a BOAC Lockheed Constellation, G-ALAM Belfast carrying mail crashed while attempting to land at Kallang Airport en route to London from Sydney. The accident killed 32 people, including eight crew.

Legacy
Kallang Airport has left several reminders of its existence. The old runway, parallel to Mountbatten Road, is now called Old Airport Road. The surrounding public flats there are named the Old Airport or Kallang Airport Estate. The slipway for seaplanes is now occupied by the Oasis Building, a structure built into the sea and, until recently, housing several restaurants. The terminal building itself was used as the headquarters of the People's Association until 9 April 2009, when it moved to its new headquarters at King George Avenue. It is not clear what will happen to the terminal building.
