On the 6th April 1969 the team (Sir Wally Herbert, Dr Roy 'Fritz' Koerner, Allan Gill and Dr Ken Hedges) arrived at the North Pole itself. It is now widely accepted that they were the first to reach the Pole by surface crossing.

Spending a year and a half constantly on the moving skin of the Arctic Ocean allowed the team to experience fully every season in the High Arctic.
Some of the pressure ridges the team encountered were several metres high and several miles long - the only choice was to chip their way through them by hand with ice-axes.
The best time for travelling on the Arctic Ocean is the winter and early spring - although travelling mostly in twilight in temperatures of -45 to -50 degrees celcius with added wind-chill could make it uncomfortable.
Inspired by the Norwegian explorer Nansen, the team made use of the natural drift of ice and set up a winter camp so that they could concentrate on scientific study, while still heading towards the Pole.
