Reminds me of the B-52, which first flew less than 50 years after the Wright Flyer, but will have been flying for about a hundred years by the time it is retired. Feels like we haven't really fundamentally changed aviation technology since the early days, just incremental improvements in materials.

Even supersonic flight was common by the 1950's. The obvious breakthroughs from here, like hypersonic flight, have been achievable but expensive and not worth it since the 1970's or so.
