That was some nice drone video footage. I was impressed with how quite it was and there appeared to be very little wind turbulence to affect its flight trajectory. Drones have been the targets of interest regarding privacy and safety concerns over the last few years. Some home owners view them as a violation of their privacy when they are used by operators to video them in the privacy of their homes. Get close enough to peek over a fence or peek throw a window and you risk your drone being shot from the sky or knocked to the ground by irate neighbors. I witnessed some police officers training some eagles to attack and destroy drones. Who can forget the drone that penetrated air space of the White House raising alarms to the secret service of a potential bomb threat or chemical attack against the President of the United States. Drones are a critical part of the U.S. Military's early detection and threat neutralizer during war time. Drones can be used for good, bad, and unintended consequences. I believe that airports have a no fly zone for drones in and around major airports. Drones are also capable of taking some beautiful landscape photographs of nature and the great outdoors.
