He participated in Jamie McGuinness' international expedition. He was also on the mountain and shot film for two documentaries. One of these documentaries was shown on TV4 in March 2007 and was called Fredrik Sträng och mysteriet på Everest (Fredrik Sträng and the Everest mystery) and was about the theory that George Mallory theoretically could have climbed the mountain as early as June 8, 1924. The other documentary was called 7 Summits and was about Fredrik Sträng's climb of the tallest mountains on each continent on the planet. Fredrik Sträng was even on Mount Everest to look for a Kodak Vest pocket camera which George Mallory's climbing partner Andrew Irvine would have carried and which hypothetically could contain a photograph of Mallory and Irvine on the summit.
