the most difficult moment was when I was ready to film a huge seal colony.
Of course I had checked the regulations and it was fine to film there. Also I was at least 100 meters from them, using the zoom.
A girl from the group I was travelling with started to shout at me from far away, something about not scaring the seals. So I gave up, and I was so mad that while bringing the drone back I pushed the left stick down instead of up. The drone hovered at about one foot over the ocean for a few seconds. Luckily the sensor worked perfectly well and prevented the drone from going down.
Very close call!
