From Rosecran Baldwin’s interview with Stan Gaz for The Morning News:
For example, the Upheaval Dome crater: The helicopter was old and worn and so was the pilot. I wasn’t nervous until we were three thousand feet above Moab, which is all treacherous rock canyons. I turned to the pilot to ask him to lean the machine sideways, and he had fallen asleep! I thought it might be a heart attack and realized it would be hard, if not impossible, for me to land because I didn’t know how to fly and there was no instruction manual. I grabbed him and shook him a bit and he woke up. We landed safe.
