Is it very loud even when planes are over 30,000 feet altitude? Can supersonic planes easily cruise at subsonic speeds when preparing to land?

- rbanffy 6y agoThey do, but the wings have a lot of drag that the engines must compensate for.
- dhosek 6y agoFrom the linked wikipedia article: >In the late 1950s when supersonic transport (SST) designs were being actively pursued, it was thought that although the boom would be very large, the problems could be avoided by flying higher. This assumption was proven false when the North American XB-70 Valkyrie started flying, and it was found that the boom was a problem even at 70,000 feet (21,000 m). It was during these tests that the N-wave was first characterized.
