Shaun O'Callaghan is the person who took this. He's not a Vulcanologist, he's an extreme sports photographer and videographer. He's taken video of the Rio statue of Jesus from a hang glider with a GoPro camera strapped to his forehead. So this really had much more to do with cool, than with safety.

Right. Obviously I confused this with similar work by volcanologists.

That was interesting to see a firework display from that perspective
some very nice and shots, thanks for sharing that.

If they cut between the land and air shots and a good back track with some changes in pitch and pace, could be a stunning visual.

I just read that the FAA is investigating the fireworks drone footage. Looks like he may have violated, according to the FAA, their drone flight rules.

I'm guessing that far more people have been hurt by errant fireworks than drones falling out of the sky. You're sending explosives into the sky with a large group of people in the vicinity, what could possibly go wrong? Typically, the crowd would't be standing directly underneath the fireworks anyway, which is where the drone would have been flying. The FAA is having quite a time coming up with sensible rules for this new technology.
