Aerial Photography and Videography Using Drones, by Eric Cheng
Drone technology is spectacular, especially when several drones communicate with another. Sooner or later they will replace helicopter rescue operations. But I am not so not so sure about democratizing dromes. Perhaps its OK, as long as it is regulated by law and does not interfere with the privacy of citizens in the free world. Including private pilots like me that hate a collision with uncontrolled hobby toys.
