This undated image provided by World View shows World View capsule and balloon spacecraft that will rise to 100,000 feet above Earth for passengers to see the curvature of the planet and the blackness of space. Space tourism companies are employing designs including winged vehicles, vertical rockets with capsules and high-altitude balloons. While developers envision ultimately taking people to orbiting habitats, the moon or beyond, the immediate future involves short flights into or near the lowest reaches of space without going into orbit.

While the lido was described as bringing “modernism to the masses” on the British coast it was just the latest example of a trend that had been developing since Victorian times – transforming seaside towns into resorts for leisure and entertainment. In the latter half of the nineteenth century, the fashion was for local authorities to build great piers stretching from the promenade out into the sea. The Eastbourne Pier, pictured here in May 1931, was erected between 1866 and 1870 to an ingenious design by Eugenius Birch, which saw the structure sitting on special cups allowing the supporting struts to “move” in bad weather. Arranged on the pier's 1,000-foot length were kiosks, a theatre, a ballroom and a camera obscura. 1931. (Photo by Aerofilms Collection via “A History of Britain From Above”)

Throughout the course of the long war in Afghanistan, Coalition troops have relied on thousands of military working dogs to help keep them safe, and make their jobs easier. The dogs are trained to detect explosives, to find illegal drugs, to search for missing comrades, or target enemy combatants. Not only are they active on the front lines, but behind the lines they serve as therapy dogs, service dogs, and loyal companions. They also share the same risks as the ground troops, suffering injuries and sometimes death on the battlefields. Gathered here are images of these dogs and their handlers in Afghanistan and back home, from over the past several years, part of the ongoing series here on Afghanistan.
