Cold War monster

 The constant desire to recapture Soviet territories or countries suitable for the United States eventually creates a monster that cruises 24,000 meters at Mach 3.   The monster's name was sr71, originally rs71, but it became sr because the then president misrepresented the name of the aircraft. When flying from 24000 meters to Mach 3, the temperature of the aircraft rises to 330-650 degrees. Eventually, all of the gas is made of titanium to cover this temperature and speed, which is still considered a great technology.The interesting thing is that the titanium used to make this was imported from the Soviet Union (which laid the foundation for Stealth's theory) because it was a monster created by the unusual situation of the Cold War, and it was soon retired after the Cold War. Now that I don't have to pay high operating expenses... However, I think the aircraft itself will remain in aviation technology history. The first stealthy consideration, titanium gas, velocity, elevation record, technical achievements to fly under extreme conditions... A book called Skunk Works written by Ben Rich shows how hard it took to make this monster. That's very interesting, too.
