The Antonov company, owner of the world's biggest plane, Antonov An-225, is considering an airport in Shijiazhuang City as a cargo transfer base in China, local airport authorities said Monday. The Ukrainian company will increase flights of the Antonov An-225 to the Shijiazhuang Airport based on Chinese market demand, as the international airport in nearby Beijing is becomes increasingly crowded, said Wang Yaqi, the Shijiazhuang airport official. The six-engine plane can carry over 250 tonnes of cargo and is mainly used for super-heavy and oversized air cargo, he said. It has a wingspan of 88.4 meters and a cargo compartment capable of holding about 80 cars. Super-heavy and oversized air cargo bound for China can be carried by Antonov An-225. After landing and unloading in Shijiazhuang, capital of north China's Hebei Province, cargo can be transported to other places in China, Wang said. According to Wang, the super plane arrived at Shijiangzhuang Sunday with 145 tonnes of giant cutting machines from Germany. The cutting machines will be transported to Tangshan City, Hebei Province. It was the plane's second landing in Shijiazhuang, the first being in 2006. Shijiazhuang Airport is the only Chinese airport the super plane has landed at.
