I think when people say this, they mean the object has travelled at twice the speed of sound. I’m not sure though! We don’t have any aeronautics people here unfortunately! Let’s see if anyone else can shed some light.

Sorry, I’m not sure what it means either, but Mike’s answer seems very reasonable…

Afraid I don’t know either – Mike’s answer sounds like it might be right though
