He was not in control at all the final 20 seconds. They are very lucky to have survived spinning into the terrain they did and walk away. I assume the NTSB probably had no clue this footage existed when the report was written and I doubt most TV shows wait two years before airing footage. Guessing the show held it back until the report was finalized. Though I don't believe they mention it in the show, the pilot was supposedly the passengers cousin. He held a private glider license with 200 hours. Guessing they thought it was a cool idea to go shoot a glider flight up in the mountains and he lacked the experience to do it successfully.
