Lockheed SR-71 Blackbird

If there was an award given for sexiest airplane alive, it pretty much could go to the Lockheed SR-71 Blackbird every single year. What does it have going for it? What doesn't it have? The Blackbird is the fastest air-breathing airplane ever, its sleek and space-age profile exudes the exotic, and its secret development and operations gave it the whole package. And speaking of exotic, Lockheed had to get fancy to make the SR-71 even possible. The innovations included the extensive use of titanium, a stealth-like small radar cross section, and loosely fitted joints between panels to accommodate the expansion of the components as the aircraft heated up while flying very fast. The big jet famously leaked jet fuel on the ramp because of this odd design feature. Although other roles were envisioned for the jet, it quickly became a reconnaissance aircraft, the best in the world. No Blackbird was ever shot down because of the plane's combination of speed, up to Mach 3.5, and altitude (up to 85,000 feet), allowing it to simply outrun the surface-to-air missiles the Soviets launched at it. The Air Force retired the SR-71 in 1998, but during the intervening quarter of a century, its fame has only grown, and its legendary shape says it all. Icon.
