Mt. Everest: On April 3, 1933, the Marquis of Clydesdale, Lt.-Col. L. V. Stewart Blacker, Lt. D. F. McIntyre, and S. R. Bonnett flew over Mt. Everest and returned with a large number of photographs. It required three and a half hours for the round trip from Purnea and one of the pilots suffered severely from the cold.
