There is arguably no aircraft that has captured the imagination of the public quite like the SR-71 Blackbird. The Blackbird has been out of commission for awhile, but there’s not one person at an air show that wouldn’t give something special to see one fly low to the ground overhead. There’s a reason for this: the SR-71, in many respects, has yet to be beaten in many of the records it has broken, and it was built in a time when America was breaking barrier after barrier in terms of scientific endeavors.
Records
Believe it or not, the SR-71 Blackbird was first built by Lockheed-Martin in the early 1960s. This is an old bird, but that hasn’t stopped her from crashing multiple records for speed. It was such a fast, high-flying aircraft that even NASA wanted to take the Blackbird on to do testing of their own. With a service ceiling of 85,000 feet, it could push up to the envelope of where the atmosphere ends and space begins.
Communication
Its biggest limitation (the thing that brought it out of retirement the first time) was the lack of a datalink. Sure, the SR-71 could cruise at just over Mach 3 in the upper stratosphere, but it couldn’t transmit any of its information back down to the ground. More inferior craft, like Lockheed’s U-2, had similar capabilities in terms of altitude but lacked any of the finesse and agility of the Blackbird. The U-2 had a downlink, though. And that’s why the U-2 is still in service and the Blackbird, for lack of a better term, isn’t.
