One of the world's eight S64F helicopters lands on Jintang Island, Zhoushan, East China's Zhejiang province, on Oct 25. The helicopter, designed by Sikorsky, a famous aircraft manufacturer in the United States, stretches over 30 meters, and has six large propeller blades and a load capacity of 11 metric tons. It's therefore called an "air crane". [Photo/zj.zjol.com]
