Nice pictures of the SR-71, also called 'Blackbird'. Main purpose was spying on the Soviet Union in the Cold War era.Here are some interesting facts about it:The USA had the CIA found a fake company in order to buy large amounts of aluminium from the Soviets, because they were the only country to have such large amounts.When on the ground, the plane would leak large amounts of fuel. That was because the planes parts would expand in high velocity/high altitude. So the parts would only fit perfect in full operational mode at around 20 km height and Mach 2,5. The sensors were able to picture around 240.000 square kilometres in 1 hour flight.Only 30 planes were build and put into operational service.Though 12 planes were lost over the years, not one single plane was actually shot down by enemy fire. The plane could simply outrun every available ground-to-air missile or enemy jet by speed AND height.The pilot and his navigator had to wear full body suits similar to space suits to counter the effects of speed and height on the human body.The whole outer hull has an active fluid cooling system, the hottest spot on the plane could reach 570° C.It holds a lot of speed and lenght records, for example from New York to London in 1 hour and 55 minutes. And it actually had to slow down, so it could be re-fueled mid-air.Edit:And here is a first person review of the plane by one of its pilots: http://sploid.gizmodo.com/5511236/the-thrill-of-flying-the-sr-71-blackbird
