Extremely interesting… as I have been following with great interest the drones used to cover the World Cup matches. (I’m still waiting to see if those drones can react fast enough when flying low to avoid collisions with well kicked soccer balls.)
In any case this video gives some idea of the observational power and surveillance capabilities of such drones. But I cannot get the video to work properly on my blog.
If you cannot then please follow this link instead: https://www.youtube.com/watch?feature=player_embedded&v=q7Maj_6eAm0
