I strikes me that the new regulation for a medical for commercial balloon operations may provide an opportunity for a natural experiment.
One can measure the rate of such accidents and fatalities prior to this regulation being put in place and after.
But what may well be the case is that these sort of events are so rare that it will be statistically impossible to show an effect, at least in less than 100 years or something like that. Has anyone computed the rate of serious balloon accidents and fatalities over the time period the NTSB has been recording them? I know that I only very rarely hear of such a thing.
