 SR-71 Blackbird

This airplane born to be the fastest airplane in the world. His origins is in the Vietnam War. It was used for spying the enemy. it could fly about 3.529 km/h and the high was 24.000 meters. If someone sent a misile, the pilot only had to acelerate to avoid it.

This american airpane was develop by Lockheed Martin for the USA Army, but it had some big problems, for example, a SR-71 desintegrated in the middle of a flight and his two pilots dead. it was a big fail and the americans start to study her estructure, where they found the cause of the accident. In addition, the blackbird was an airplane too expensive to keep even for american army.

In conclusion, his last flight of the legend blackbird, was in 1999, an airplane that showed the world that we needn´t use weapons for being a legend in the history of the aviation.
