How Fast an SR-71 Spy Plane Can Really Travel Will Shock You
Guesses?

The SR-71, the most advanced member of the Blackbird family that included the A-12 and YF-12, was designed by a team of Lockheed personnel led by Clarence “Kelly†Johnson, then vice president of Lockheed’s Advanced Development Company Projects, commonly known as the “Skunk Works†and now a part of Lockheed Martin Corp.
The Blackbirds were designed to cruise at “Mach 3+,†just over three times the speed of sound or more than 2,200 miles per hour and at altitudes up to 85,000 feet.
Now when talking about SR-71 probably the most frequently asked Blackbird question is-how high and how fast does it really fly?
