The fastest military jet in the world

With it`s first flight in 1964 this reconnaissance aircraft has engaged the interest of people with it`s iconic design and with the possibility of what it can do. In 1976 Captain Robert Helt piloted the Lockheed SR-71 Blackbird and broke the record of flying in the highest altitude in a sustained flight. Captain Helt managed to fly in a altitude almost of 26 000 m and this record was not broken to this in a sustained flight. The same day different pilot Brian Shul in a different Blackbird set an incredible speed record of Mach 3.3 which is 3,529 km/h. The Lockheed SR-71 Blackbird has retired in 1998 and only 32 of the were built but is is to this day one of the most iconic aircrafts ever built.
