Want to see some accident stats from an official source then look here on slide 15:

I would strongly suggest that the accident stats for Reaper/Predator in recent times are better than some UK fast jet types and also UK light aircraft looking at this analysis? Even if these stats have been 'cherry picked' it would appear that manned/unmanned accident rates are of the same order of magnitude.
