Concorde is gone, what will replace it? Time for a Geek Out! Richard talks about the aeronautical evolution that led to supersonic airliners, Concorde being the big one that flew from 1976 to 2003. What went wrong? Why did it stop flying? Besides the technological challenges, it all comes down to the sonic boom and laws that make it illegal to fly a civilian aircraft above the speed of sound. Richard talks about how technology has advanced enough now that aircraft can mitigate their sonic boom with specific shapes and flying capabilities. However, in the end, supersonics only get you there faster, typically for more money. Would you pay for to go faster?
