Wow, amazing footage! I can't believe he flew without a permission AROUND and OVER Vlads homebase. Even the traffic looked pretty normal, not a single horrific crash was seen in the whole movie!
No way would this have been permitted in the USA, but my guess is Alex had permission to do this in Moscow or he'd be in a labor camp right now.
Putting aside the legal question the video is spectacular and demonstrates what's possible with a UAV in the right hands if you have all the permissions.
One last thing ... boy does it look COLD in Moscow!!!!!!!!!
