“The Lockheed SR-71 “Blackbird” was an advanced, long-range, Mach 3+ strategic reconnaissance aircraft. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by the Lockheed Skunk Works. Clarence “Kelly” Johnson was responsible for many of the design's innovative concepts. During reconnaissance missions the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outrun the missile”. – Wikipedia

The “Paolo Di Paolo: Lost World” exhibition presents more than 250 largely unseen images from the photographer’s archive. Di Paolo chronicled life in his country as an economic boom followed the destruction of the second world war. Although those were the years of la dolce vita he was an anti-paparazzo – he shunned the salacious and respected his subjects. The exhibition is at MAXXI, the National Museum of 21st Century Arts in Rome until 30 June. Here: Viareggio in 1959. (Photo by Paolo Di Paolo/National Museum of 21st Century Arts)
