Imagine being lost for 75 years in the most inhospitable place on Earth. When explorers finally found George Mallory, they found a man frozen in time. But they didn't find the one thing that could change history forever: his camera. Did Mallory and Irvine conquer the Second Step and reach the summit before the mountain claimed them? We explore the chilling theories and the physical evidence left behind in the snow. #ExpeditionFiles #DiscoveryUK
