'Lockheed SR-71 Blackbird' is the fastest manned aircraft in the World. Originally built as an advanced, long-range, strategic reconnaissance aircraft, it reached unheard speeds of 'Mach 3+' which is equivalent to three times the speed of sound or '3000 kilometers per hour'.
Lockheed Project Background
This 'Lockheed SR 71 Blackbird' project succeeded from the reconnaissance project named 'Lockheed A-12 ' in 1960's. Currently this aircraft holds two world records in its wings. One for the 'fastest manned aircraft' and other for the 'Highest flying operational manned aircraft'. During its operational period, SR-71 operated at high speeds evading any missile by just 'outrunning through its powerful afterburner which produced speeds nearly reaching Mach 3.5!'.

Lockheed Aircraft World Records
On 28th July 1976, Lockheed SR-71 with a serial number 61-7962 broke the World record for 'Highest flying aircraft' by flying at an incredible height of '25.929 kilometers' which is nearly 26 kilometers high in the stratosphere.
Note :There is a significant difference between altitude records set by different aircraft because this aircraft had a sustainable flight at those height but not in zoom climbs.
Along with this record, that same aircraft set an 'absolute speed record' of '3,529.6 km/h'. (nearly mach 3.5).
These aircraft also holds the 'Speed Over a Recognized Course' record by flying a record distance of 3508 miles at a speed of 2,310 km/h between London and New york and finishing it at an elapsed time of 1 hr 54 minutes on 1974.
If we compare the results along with other aircraft which took part in this competition, results will be mind-blowing. Concorde had set a record time of 2 hours and 52 minutes and Boeing 747 at 6 hours : 15 minutes.
