SR-71 Blackbird

The fastest air-breathing manned aircraft ever built/Aircraft

The Lockheed SR-71 Blackbird flew so fast that its standard evasive maneuver against missiles was to simply accelerate. Cruising at Mach 3.3, the titanium airframe would expand several inches from thermal heating, and the panels were designed to fit loosely on the ground, meaning it literally leaked fuel until it got hot enough to seal. It set the speed record for a manned air-breathing aircraft in 1976, and nobody has beaten it since.
