The video above has been on the internet for years and is nothing new. What is new, is that recent unclassified documents confirm that it is real and give additional details of the incident.
According to Spiegel Online, the clip was taken from an 88lb LUNA Drone that shows the UAV about to strike an Ariana Airbus A300 aircraft while flying over Afghanistan. The German drone came with-in about six feet striking the left wing and could have potentially caused an accident. Although an object that size, hitting the end of the wing, would not necessarily mean the aircraft would crash to the ground.
After passing the jetliner, the drone hit the A300’s wake and crashed in Kabul.

So there IS a reason to be cautious of drones operating in our skies! That Airbus carries a lot of souls. I hope safety is emphasized in future drone design.
