Given US Army's latest stat, FY 2013, of 0.72 Class A mishaps per 100,000 hours compared to Reaper 3.4 and Predator 4.2 (to put them on the same rate of use basis, 100,000 hours) and the Army flies mostly helicopters whereas Reaper is a fairly benign high aspect ratio fixed wing aircraft ... the numbers don't look as good as you might think.
