SR-71 Blackbird – still world record holder

The SR-71 Blackbird is still the world record holder in flight air speed. This is accepted by Fédération Aéronautique Internationale (FAI). The record is from 1976 and still stands astonishing 3530 km/h, over Mach 3.2+. This at an altitude of 80 000 feet! There are other aircrafts that have travelled in much higher speeds, but they don’t fit in the criterias, for example the Boeing X-43a at 11 270!! km/h (7000 mph) or Mach 10+ yes 10 times the speed of sound! But we are here to salute the SR-71 Blackbird and we do it with honor!
I found a video on youtube check it out! Nostalgic

    The Climb rate is 60 meters each second, or 12 000 feet per minute… so in 8 minutes it reaches the cruising altitude of 88 000 Feet, / Linus
