First, a detour. Clarence "Kelly Johnson" of Lockheed Martin Skunk Works was given the task of building the ultimate reconnaissance plane during the Cold War. He knew he needed to create a supersonic aircraft that would fly higher and faster than ever, but also leave the least possible mark on enemy radar screens.
Kelly was well aware that supersonic flight would bring with it a lot of heat.www.paybestwatch.org The aluminum body of a traditional aircraft would become jello-like the moment it exceeded Mach 2.6. Kelly wanted his aircraft to be able to exceed Mach 3.
It wasn't a big problem. Kelly knew his solution: titanium. Its lightness would allow it to fly higher than ever before, and its melting point (more 1,650degC) meant it could withstand temperatures beyond Mach 3.
It wasn't easy to get titanium in the US. Kelly's only option for obtaining the titanium he needed was to go beyond the Iron Curtain and purchase it from the USSR.
The CIA was able to collect the titanium Kelly needed. On the 22nd December 1964, Lockheed's Burbank facility in California unrolled the dark-winged creature we now know as the SR-71 Blackbird. This was the first aircraft to be made largely of titanium. More than 90% of the SR-71 is titanium.

Now that we're back on the topic at hand, you should know by now the journey of the tag heuer carrera day date replica Speedmaster to become the "Moonwatch". Let me remind you a few details from the NASA document,omega seamaster replica which was created after they tested the three tag heuer carrera day date replica watches.
NASA wrote in a qualification document dated March 19,65 that "the results of the operational evaluations of the astronauts showed a unanimous preferential preference for the tag heuer carrera day date replica Chronograph over the two other brands due to better accuracy, reliability and readability, as well as ease of use."
