The pictures broadcast around the world of a manned Boeing CH-47 Chinook flying over the stricken, radiation-emitting Fukushima nuclear plant in Japan in the early days of the ongoing disaster filled aviation experts with horror. Aviation industrialists and observers who are aware of the capabilities of current unmanned aerial vehicles (UAV) saw this situation as the most logical and appropriate use of current proven technology. Surely it would only be a short time before this lifesaving (as far as people battling to control this desperately bad situation were concerned) technology was deployed? They watched and waited. But nothing happened.
