       | until reading this book. The SR-72 would cruise at Mach 3, or
       | three times the speed of sound. It would do this at 80,000 feet,
       | over twice the traditional cruising altitude of a 747. Even at
       | this height, where the temperature is -60degF, friction would
       | cause the fuselage to heat to 600degF. This would melt
       | traditional aircraft, so the plane was built with titanium
       | (ironically supplied by the Soviet Union). The Blackbird used to
       | overfly North Korea five days a week in just ten minutes.

           | Two things:
           | 
           | - Your bowl is most likely not pure titanium and is probably

       | Ground knew who was where, so it asked my grandfather, "would you

       | an F15 pulled up alongside him, pointed at an upward angle and

       | rocketed away.
       | 
       | Most likely that day, the F15 was the fastest thing in the air
       | for several hundred miles.

         | a small plane got on the radio and said "how fast am i going"
         | 
         | the tower said "you are going fast"
         | 
         | and then a bigger plane got on the radio and said "haha i think
         | i am going faster how fast am i going"
         | 
         | and the tower said "you are going a little faster"
         | 
         | and then a jet fighter was going really fast and talked like a
         | really cool guy and said "hey there, I sound like a cool guy,
         | tell me how fast I'm going"
         | 
         | and the tower said "you are going very fast" but he sounded
         | totally normal
         | 
         | And then I wanted to say something but that was against the
         | rules, and then the other guy in my plane said "hey tower, are
         | we going fast"
         | 
         | and the tower said "yes you are going like a million fast" and
         | then the guy in my plane said "I think it's a million and one
         | fast" and then the tower said "lol yeah ur plane is good"
         | 
         | and then I said "did we just become best friends"
         | 
         | and the other guy said "yes"
