Yes, the heart raced. I made a couple hundred meters through that frozen forest completely cut off by the fog and I regret not starting recording earlier.Wow! I bet that had your heart racing! I was nervous just watching.
What did you do when you got into the white out? Did you climb to make sure that you were out of the trees before your 'retreated'? Were you manually flying back home rather than using the RTH?
Thanks for sharing - and for the little adrenaline rush this morning!
