The following video shows flying up the Kern River from the pilot's eye view, though it doesn't show the section of canyon you were in- https://www.youtube.com/watch?v=hU4PiAYSOaE
The last portion of the video shows flying down Rainbow Canyon where a Navy pilot crashed last month. I've watched jets scream down that canyon while I was hiking down in its depths. I imagine the difference in experience between the pilot and me is similar to that between a falcon and a dung beetle. I'd love to see it as the falcon for once.
