[citation needed] In late 1999, to mark the 50th anniversary of the founding of the PRC, the airport underwent a new round of expansion.20 September 2004 saw the opening of the renovated Terminal 1 which, at that time, only handled China Southern Airlines' domestic and international flights from Beijing.At its opening, the new Terminal 3 was the largest man-made structure in the world in terms of area covered, and a major landmark in the developing Chinese capital.The loan was the largest ever granted by the EIB in Asia, and the agreement was signed during the eighth China-EU Summit held in September 2005.[10] Following the 2008 Summer Olympics and the addition of adding the new terminal building, Beijing Capital overtook Tokyo Haneda as the busiest airport in Asia based on scheduled seat capacity.[15] Terminal 1 reopened for a second time on 27 June 2008, and became the operational base for all domestic flights operated by the HNA Group including those of Hainan Airlines, Grand China Air and Tianjin Airlines, while all HNA Group's international, Hong Kong, Macau, and Taiwan flights remain in Terminal 2.On 20 July 2013, a man in a wheelchair detonated small homemade explosives in Terminal 3 of the Beijing International Airport.The transportation center has designated traffic lanes for airport buses, taxis, and private vehicles.Under the white strips, the basic color of the ceiling is orange with light to dark tones indicating where a passenger is inside the building.Many traditional Chinese elements will be employed in the terminal's interior decoration, including a "Menhai", a big copper vat used to store water for fighting fires in the Forbidden City, and the carvings imitating the famous Nine-Dragon Wall.The terminal provides 72 aerobridges or jetways and is further complemented with remote parking bays that bring the total number of gates to 150.This capability was proven when Singapore Airlines briefly offered A380 flights to Beijing in August 2008 during the Summer Olympics.In conjunction with the construction of the new terminal, Bombardier Transportation installed a 2 km (1.2 mi) automated people mover which connects T3C and T3E via T3D in a 2–5-minute one-way trip.[86] The line uses Innovia APM 100 vehicles running at 6-minute intervals at a maximum speed of 55 kilometers per hour (34 mph).[87] New Innovia APM 300 vehicles is being delivered to Beijing Capital International Airport Terminal 3 People Mover in July 2021.The airport buses accept only paper tickets that are sold at each terminal and certain bus stops in the city.The airport also offers intercity bus services to and from neighboring cities including Tianjin, Qinhuangdao, Baoding, Langfang and Tangshan.[106][107] On December 5, 1968, the airport was the site of two fatal accidents in less than 24 hours; On August 27, 2019, an Air China Airbus A330 caught fire while parked at the gate during boarding.
