    Surely that’s not what’s impressive about it? We can already do that right?

        I feel like I’m taking crazy pills.

        The speed of sound is 343 m/s, 767 mph. This description is Mach 5, 5x the sound barrier.

        An F-22 can go 1500 mph.

        Apparently the first airplane to break the sound barrier was Bell X-1 in 1947.

          I think the intention is to highlight it as a milestone in the development of this aircraft. If you read the article, sounds like it hasn’t even been on a test flight yet.

      Hypersonic is 5x the speed of sound. SR71, F22, F35 none of them could go that fast. Or at least were designed to go that fast. Get an aircraft to reliably and consistently go 5x the speed of sound is a huge milestone.
