It maybe nice footage, but it is also pretty dangerous and illegal.
I use drones to inspect gutters and roofing projects and showed this to a friend of mine who is a professional drone operator, with insurance and approved by the CAA to operate.
He said ‘Illegal on so many levels. Breaks many of the basic drone laws that are there to keep people safe. I won’t bore you but drone should be at least 50 meters away from people and property and 150 meters away from crowds or built up areas (London) and don’t overfly. Very dangerous to anyone near it, if there was a malfunction etc. Suspect if the operator was willing to do this with such abandon then having insurance would not have been a consideration’
Best not promote this kind of activity.
Not an advert, but as he was kind enough to share his thoughts, a link to his website -
