SR-71 (Lockheed)
The SR-71 is an old American spy airplane from the USAF but is no longer operational with the United States Air Force. The SR-71 is also used by the American aerospace organization NASA for scientific research.
6-day war
The SR-71 was used during the 6-day war in Israel. The US send a SR-71 in all secret to Egypt and Israel to gather intelligence. The SR-71 flew from the US to the region near Portugal where a tanker from the Portugal refuels the SR-71. Only the crew of the tanker knew about this, here for they lie to the air control when they asked why they changed from their route. After refueling the SR-71 flow through Egypt and Israel. Because also Israel didn't know about this they began shooting at the unidentified aircraft. The SR-71 made his photographic's above Israel and Egypt with more than mach 4 and flown back through the US. The information was to support the President of the United States with the true information what was going on so he could made his decisions etc. The SR-71 is stationed at the secret air force base Area 51. This base is called secret because almost everyone knows about this base but the US department of defence has never admitted this base.
 

Technical
The SR-71 is a delta-wing, double seater airplane which is powered by 2 axial-flow turbojet engines. The aircraft was specially developed to operate at high altitudes and at high supersonic speeds. The SR-71 has very thin wings, twin canted rudders mounted on top of the engine nacelles, and a pronounced fuselage "chine" extending from nose to the leading edge of the wing. The propulsion system uses movable spikes to vary air inlet geometry.
Surface controls are ailerons and rudders which are operated irreversible hydraulic actuators with artificial pilot control feel.
The SR-71 can be refueled either in-flight or on the ground through separate receptacles that feed into a common refueling line. A drag chute is provided to augment the six-main wheel brakes. All U.S. Air Force aircraft were painted black to reduce internal temperatures when flying at high speed.
