"although its characteristic sonic boom was no longer heard above populated areas by the 1990s in the wake of complaints from those whose windows had been shattered."
Concorde was never allowed to fly supersonic over land during its commercial operating career. On transatlantic flights the aircraft would fly subsonic over land before transitioning to supersonic mode over the Bristol Channel. Whilst the boom was audible, and occasionally loud enough to rattle windows in North Devon and North Cornwall, it certainly was never loud enough to shatter windows. The only damage that was attributed directly to repeated sonic booms from Concorde was the loosening of the pointing between slates on some roofs.
