You've done a very nice job and seem to really have a handle on piloting your drone, everything very smooth. Even after two years of flying I don't have the courage to get so close to objects and structures and definitely stay away from flying under bridges as there are too many tales of drowned drones due to the inability to sense water.
Since you've done such a great job I'd like to ask you if there are any tips for identifying how close you are to structures to fly so close and what your appproach is to flying under bridges? Obviously you have to have a command of the space and drone's vector off the screen. I feel that I'm missing those elements in my flying and film. I just don't seem to have a handle on the spatial things and how much room I have to pass through things. To go under a bridge you can't just be standing behind the drone watching it go through. TIA
