Good progress for industry... but are we any time in future going to have pilot less helicopters taking on missions that involve decision making, inching to the limits of aircraft envelope, considering factors that may not be put into an algorithm for reasons of their subjectivity etc...
Pilot less machines have limited employability restricted to scientific experiments (not related to aerodynamic stability and control, performance etc) and may be considered as an extension of robotic league in aerospace.
Well ... at least lets start arguing now......
