Whether you’re a fan of high-speed aircraft or not, you’ve heard of the famous SR-71 Blackbird. Considered to be a reconnaissance aircraft or “spy plane” because it could fly so high and so fast that it was extremely difficult to detect. Originally designed back in the early ’60s, it made its first flight in 1964 and then put into service two years later where it remained until retiring in 1999.
