Just 20 years before it first flew , people were dying trying to reach those speeds in a g-suit.

Yeah , it was expensive but as every new technology. You would get inside, reach your seat, steward came in : *sir, you want a glass of champagne?* , of course you would say yes , and also ask for that filet mignon with strawberry sauce that you saw on the menu. Chillin' at mach 2 , 17 km up in the sky .
