Unless it's secret and involves the MoD or the armed forces. Then they'll say nothing. Plus everyone will now chatter about a 'mystery boom'.Yes- can't find anything specific but it seems to be against aviation rules and guidelines, rather than law, to cause a sonic boom over land unless there are "operational reasons" for doing so.
