In my opinion, Mallory and Irvine did not reach the summit. For one, Noel Odell, the expedition’s geologist and sole eyewitness to the climbers’ fate, had found the entire North Face under cloud on that noon of June 8 at 12.50 pm. When the clouds had lifted slightly, he noted in his diary, he distinctly sighted the two figures near the Second Step which they had actually planned to reach around 8 am. They were thus four hours late in starting from the last camp. In such a situation, logistically their chances of getting to the top were quite poor.
