Ignoring the sarcasm in a previous post, I wonder why they would want to fly that route in a single engine aircraft?
Having flown eight years in the high Arctic and God only knows how many hours in South America around both sides, I have learned to respect the weather and the vastness of the areas they are going to fly over.
So using the bottom line which is risk assesment would I do it in a single engine aircraft ?
No.
