The SR-71 was unofficially named the Blackbird; its crews often called it the Sled, or the Habu (&quot;snake&quot;). The SR-71 line was in service from 1964 to 1998. Clarence &quot;Kelly&quot; Johnson was the man behind many of the design's advanced concepts. The SR-71 was one of the first aircraft to be shaped to reduce radar cross section. However, the aircraft was not stealthy and still had a large enough radar signature to be tracked by contemporary systems. The aircraft's defense was its high speed and operating altitude; if a surface-to-air missile launch was detected, the standard evasive action was to simply accelerate. Thirteen aircraft are known to have been lost, all for non-combat related reasons.<br><br><img src=http://www.gearthhacks.com/images/new/080505/75310971.jpg>
