I didn't notice it mentioned here, so thought I'd post. When you look at this vid, and the follow up he did later, one of the big takeaways for me is that a series of instructors seem to have failed. I believe she had 400 hours flying, which is way more than me, but I feel I am more proficient. Tragic that her father died with her.
Because she was doing it for YouTube, she had a number of cameras on board, so a good chance at least one will be recoverable (only the SD card needs to still function). That's going to be both informative and harrowing for the investigators.
