Number 10. BELL H-13 SIOUX was a two-bladed, single engine, light helicopter built by Bell Helicopter. Westland Aircraft manufactured the Sioux under license for the British military as the Sioux AH.1 and HT. In 1947, the United States Air Force ordered the improved Bell Model 47A. Most were designated YR-13 and three winterized versions were designated YR-13A. The United States Army first ordered Bell 47s in 1948 under the designation H-13. These would later receive the name Sioux. The Bell-built H-13 B is seen airborne in this April 29, 1951 photo. The helicopter is equipped with a 173 horsepower engine, cruises at 85 miles per hour, climbs 900 feet in a minute and has a service ceiling of 11,500 feet. (Photo by AP Photo)

Ko Min, 26, manually extracts oil from one of three 300 feet deep wells he works on in the Minhla township of the Magwe district October 27, 2013. Everyday, Ko Min makes around $30 extracting crude oil from three small wells after he bought rights to use them for close to $1000 from a farmer who owns the land. In Myanmar, an impoverished country rich with natural resources, people from poor communities find ways to supplement their income by exploiting such resources, such as the Minhla township, traditionally rich with oil, often using primitive and dangerous methods.

Ice Age – Tibet, China. “This is the Chinese version of the blue ice lake, Pumoungcuo, at an altitude of 5,070 metres (16,600 feet). This lake in Tibet freezes every winter. At night, under the low temperatures of -20C, you can listen to the sound of the ice cracking while capturing the most beautiful winter sky. The blue ice surface and dazzling Orion constellation create a fantasy landscape. I felt so happy to have the stars as my companion on this magical night”.
