Being a newbie to this please forgive me if this isn't an issue, but when they're flying over the train, isn't that against the regulations set forth by the FAA?
I've noticed the majority of YouTube crash videos are people using the drone beyond what it was designed for or explicitly against FAA regulations. Most seem to think nothing of it and expect their drone to be repaired or replaced for free.
Watched one video of a guy that borrowed the drone, videoed himself on his motorcycle on the street with the drone flying through power lines. Didn't make it very far before it hit a power line. I'd be peeved if I had a friend that stupid. Dude actually seemed to the skydio owed him a new drone. Comments were off so assume there were several people that pointed out the multitude of errors he made.
