> Are people forgetting about how incredibly loud is a sonic boom? Is it? I lived in Kansas in the 1960s. Sonic booms from the AF base were common. They weren't that loud. Electric storms (a regular in Kansas) were considerably louder. > The Concorde burned fuel (passenger miles per liter) at roughly twice the rate of non-supersonic aeroplanes. 5-7 times as much. My dad said when he pushed his jet supersonic, you could watch the gas gauge unwind. |

Did your dad fly military jets? Most older jets can't supercruise, i.e. go supersonic without using afterburners, and afterburners consume unholy amounts of fuel. Concorde did consume quite a lot of fuel per passenger mile, but it could supercruise.
