Long, long ago a Canberra dropped a practice bomb on the Theddlethorpe ranges.
It went rather wide, landing on the "Prussian Queen" pub (to be exact, on the Ladies, luckily unoccupied at the time). It destroyed the porcelain, but the seat was recovered and given pride of place behind the Lounge Bar.
Questions were asked in the House (there is a Hansard record, which I cannot readily trace now). Older readers may recall the incident (1950s).
Just thought I'd mention it.
