November 28th will be the 40th anniversary of the Erebus disaster which shook our nation and took 257 lives when an Air New Zealand sightseeing flight crashed into a mountain in Antarctica.
A Royal Commission of Inquiry later revealed 'an orchestrated litany of lies' designed to cover up the real reasons for the crash.
Sarah Myles' grandfather Frank Christmas, a keen amateur photographer, died in the tragedy. She's written a book Towards the Mountain, which weaves together the stories of Frank, his fellow adventurers and the first responders on the scene.
