Hi-Mems – What? Back in December of 2008 (issue 47) we spoke of pilotless aircraft in general. We wondered why, given images of science fiction pilot Col. Wilma Deering (Erin Gray from the TV series Buck Rogers), they’re so intent on ridding the sky of pilots. And regular readers of these columns know we have also touched on UAV’s a time or two (Issue 48). But it’s been two years and although much work has been accomplished in both fields; perhaps more intense have been the efforts to develop micro UAVs.
