10 Things You Dont Know AboutBlack bird ..!
http://jetlinemarvel.net/http://jetlinemarvel.net/2015/11/24/10-things-you-dont-know-about-black-bird-2/1. The SR-71 Blackbird aircraft was built by Lockheed Martin and took its first flight
in 1964. It was retired by NASA in 1999. The SR-71 has been given several
nicknames, including Blackbird and Habu.The SR-71 served with the U.S. Air
Force from 1964 to 1998.
2. It is the fastest planes that ever took flight. The official fastest record it holds is
2,193.13 mph on July 1976.
SR-71s first arrived at the 9th SRWs Operating Location (OL-8) at Kadena Air Base,
Okinawa on 8 March 1968.These deployments were code named Glowing Heat,
while the program as a whole was code named Senior Crown. Reconnaissance
missions over North Vietnam were code named Giant Scale
3.Over 4,000 missiles were fired at the Blackbird in the 25 years it was flown, but
none ever hit it. The Blackbird was just too fast and its evasive tactic was just to
speed up until the missile couldnt keep up with it.
A total of 32 aircraft were built; 12 were lost in accidents and none lost to enemy
action.Considering all accident , Only one crew member, Jim Zwayer, a Lockheed
flight-test reconnaissance and navigation systems specialist, was killed in a flight
accident.The rest of the crew members ejected safely or evacuated their aircraft on
the ground.
4. The plane was covered in over 60 pounds of black paint because the black
helped cool down the plane by up to 86 degrees. Traveling at over Mach 3, the
plane could hit as high as 1,000 degrees without the black paint dissipating the
heat.
Finished aircraft were painted a dark blue, almost black, to increase the emission of
internal heat and to act as camouflage against the night sky. The dark color led to
the aircrafts nickname Blackbird.The outer windscreen of the cockpit was made
of quartz and was fused ultrasonically to the titanium frame. The temperature of
the exterior of the windscreen reached 600F (316C) during a mission.
5. It was built to fly up to Mach 3.4 speeds (approx. 2,500 mph on land).
It has held the world record for the fastest air-breathing manned aircraft since
1976; this record was previously held by the related Lockheed YF-12.During aerial
reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow
it to outrace threats. If a surface-to-air missile launch was detected, the standard
evasive action was simply to accelerate and outfly the missile.

6. The plane required a large amount of titanium to be built so the CIA created fake
companies around the world to buy metal from the USSR, which was the biggest
supplier, as well as the United States enemy at that time.
The red stripes on some SR-71s were to prevent maintenance workers from
damaging the skin. Near the center of the fuselage, the curved skin was thin and
delicate, with no support from the structural ribs, which were spaced several feet
apart.
