It is a big shame when someone with his "credentials" does something like this. I suspect in his case this is not an isolated instance.
His credibility took a large tumble with his South Pole (Antarctica) debacle. After being refused permission to land there he decided to go anyway on the premise he was attempting to fly from New Zealand to South America but due to "unforseen head winds" he had to "divert" to Antarctica. Any pilot with his experience (knowing that Antarctica was out of bounds) would have had PNR and ETP points sorted out and updated a he went along to avoid having to land at Antarctica. Then he had the gall to try and accuse the New Zealand base at Scott Base of being unhelpful when he turned up unexpectedly.
