From the time it became operational in 1964 until it was retired in 1989 (and then retired again in 1998), the Lockheed SR-71 Blackbird spy plane was unparalleled it its ability to fly fast, fly high and literally outrun the missiles enemy defenders fired to bring it down.
In fact, during its entire operational career - 3,551 mission sorties totaling 11,000 hours (including 2,750 mission hours being flown at Mach 3) - no Blackbird was ever felled by enemy fire.
That's no surprise, of course: You can't hit what you can't catch.
