Microsoft co-founder Paul Allen has spent the last six years working on a giant aircraft capable of launching rockets to space. Today, his company Stratolaunch Systems literally rolled that plane out of its hangar in the Mojave Desert for the first time ever.

“G.I. Joe is a line of action figures produced by the toy company Hasbro. The term G.I. stands, in popular usage, for Government Issued and after the First World War became a generic term for U.S. soldiers. The origin of the term dates to World War I, when much of the equipment issued to U.S. soldiers was stamped “G.I.”, meaning that it was made from galvanized iron. The development of G.I. Joe led to the coining of the term “action figure”. G.I. Joe's appeal to children has made it an American icon among toys”. – Wikipedia. Photo: Vintage G.I. Joe figurers are on display at the 2003 Hasbro International G.I. Joe Collectors' Convention June 27, 2003 in Burlingame, California. (Photo by Justin Sullivan/Getty Images)

A drone operated by paramilitary police flies over the site of last week's explosions at Binhai new district in Tianjin, China, August 17, 2015. Many operations have resumed at China's Tianjin port, trade sources said, after explosions last week that killed more than 100 people and disrupted business at what is an important oil, gas and bulk import harbor for Asia's biggest economy. The explosions on August 12 led to the disruption of all chemical and oil tanker discharges at the port, and imports of iron ore were also affected. (Photo by Kim Kyung-Hoon/Reuters)

Films that are being screened are advertised in a makeshift cinema located under a bridge in the old quarters of Delhi, India May 25, 2016. A makeshift cinema hall under a 140-year-old bridge in the Indian capital is allowing poor rickshaw pullers and migrant labourers to escape daily hardship and sweltering heat into a world of Bollywood song, dance and romance. With the rusty iron floor of the bridge as its ceiling and some old rags acquired on the cheap from a nearby crematorium serving as curtains and floor mats, the cinema shows four films a day.

Photographer Gregg Segal travelled the world to document children and the food they eat in a week. Partly inspired by the increasing problems of childhood obesity, he tracked traditional regional diets as yet unaffected by globalisation, and ironically, found that the healthiest diets were often eaten by the least well off.
