Lockheed SR-71 Blackbird

I would like to introduce you about a  very interesting and mysterious aircraft and the details of the same are as follows :
The Lockheed SR-71 "Blackbird" is an advanced, long-range, Mach 3+ strategic reconnaissance aircraft[1] which was in service with the U.S. Air Force from 1964 to 1998.It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by the Lockheed Skunk WorksClarence "Kelly" Johnson was responsible for many of the design's innovative concepts.The Lockheed A-12, designed for the Central Intelligence Agency (CIA) by Clarence Johnson at the Lockheed Skunk Works,[9] was the precursor of the SR-71.




The aircraft is  designed  superbly as follows:
The aircraft has  high temperature materials to overcome the problem of high temperatures generated.The airframe of the SR-71 is made of titanium.Lockheed uses many guises to prevent the Soviet government from knowing what the titanium was to be used for. In order to control costs, Lockheed uses a more easily worked alloy of titanium which softened at a lower temperature.
