Since the demise of the Royal Tournament, the Field Gun competition has become even more of an anachronism. It has always been unsafe, it's just that now there are no professional field gunners - something to do with cost-cutting.
The thing about safety is that if everything is safe, it means life becomes bland and uninteresting. Even the boring continual references to one particular new entry training establishment bemoan the loss of the mast manning ceremony and that was for reasons of safety, as well.
Can we return to the days when, if a job needed to be done, it was done by the first person able to do it, whether standing on a chair, rather than a step ladder, and not having had the minutest specific training course to change a lightbulb or whatever? Probably not, but what a sad, inefficient, litigious society we now live in.
