The Northeast Airlines DC-3 actually crashed on the side of Mt. Success, just below the summit, on November 30, 1954 and survivers were rescued two days later, I think. The flight, a puddle jumper from Boston was heading to Berlin. On board were the pilot, co-pilot, a dispatcher, a stewardess, and several passengers. All survived the initial crash, but two, the co-pilot and dispatcher, died before rescuers arrived. There is an interesting account of this accident in "Adventures of a Yellowbird" which is out of print. There is a bushwack to the site off the trail south of the summit.
