So I end up, every time, concluding that these things are, just about every time, a bunch of academics playing with toys
Still holds true in commercial aviation. A new system is developed, does not work, their theory is my pain in the ass as theoretical systems become functional in operation from the response of the operator.
Little thread drift off UAV.
On target, UAV reliability was crap on operating units, little life liability and military freedom "cost" being a factor. Once the cost issue finally was accounted for, I believe the operational requirements were further scrutinized giving better reliability. Are you flying an aeroplane or flight sim/toy aircraft.
