I just finished reading the article in Aviation International News, unfortunately it's not on their website, but might be after the next issue. You should absolutely find a copy of this to read this amazing, well written and researched story.
This story is truly remarkable and the crews that performed it should be recognized for what they achieved. Stories like this are generally relegated to old Aviation books, not contemporary news reports!
Calgary to the South Pole, during the Antarctic winter, in a Twotter to perform a medevac - now there's an amazing story.
Congratulations to all at Ken Borek for achieving this amazing feat. Great job......
