residential precincts on either side of Old Airport Road are collectively called the "Old Kallang Airport Estate". The conserved Kallang Airport building was one of the hosting venues of the 2011 Singapore Biennale. The decision to hold this art festival at the old Kallang Airport was controversial, with negative opinions surrounding the building's poor ventilation and inaccessibility. There are plans to redevelop the Kallang Airport area into a commercial hub, along with the nearby Kallang riverside. This proposed plan is known as "Old Airport Square", as envisioned by the Urban Redevelopment Authority (URA) Master Plan 2008. Predating the Kallang Airport, Singapore's first aircraft landing took place at the Farrer Park Field on 4 December 1919, when Captain Ross Smith touched down in a Vickers Vimy along with three other crew members. Sports Kallang occupies an important position in Singapore's sporting culture and history, particularly due to the several iconic sports locations sited within its boundaries, as well as the numerous high-profile sporting events held there. Famous sports facilities include the old National Stadium, the Jalan Besar Stadium, the Farrer Park Field, and the Singapore Sports Hub. Kallang is notable for being the location of the former National Stadium (nicknamed the "Grand Old Dame of Kallang") and the new Singapore Sports Hub which was built on the same site to replace the former. The latter is the flagship development in Kallang and includes the new National Stadium, the Singapore Indoor Stadium, the OCBC Aquatic Centre, the OCBC Arena, the Kallang Wave Mall, the Singapore Sports Museum, the Sports Hub Library, as well as several other sports facilities. The Singapore Sports Hub is the only "Tier 1" facility under the Sports Facilities Master Plan. The Singapore national football team is based at the new National Stadium. Aside from being a traditional location for hosting the National Day Parade (NDP), the old National Stadium also played host to numerous notable cultural and sports events, including those of the Malaysia Cup, where loud cheers and stamping of feet gave birth to the famous "Kallang Roar". The famous "Kallang Wave" is a type of Mexican wave that often took place in the old National Stadium during those games. Both the Kallang Roar and Kallang Wave are considered to be symbols of national unity. The 1973, 1983 and 1993 Southeast Asian Games used the old National Stadium as its ceremony venue.
