Welcome to popular Wiki of the Day where we read the summary of a popular Wikipedia page every day.
With 389,781 views on Monday, 9 July 2018 our article of the day is Lockheed SR-71 Blackbird.
The Lockheed SR-71 "Blackbird" is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. 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 were detected, the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed with a reduced radar cross-section.
The SR-71 served with the U.S. Air Force from 1964 to 1998. A total of 32 aircraft were built; 12 were lost in accidents, but none were lost to enemy action. The SR-71 has been given several nicknames, including "Blackbird" and "Habu". It holds the world record for the fastest air-breathing manned aircraft since 1976; this record was previously held by the related Lockheed YF-12.
