Did Chinese woman who climbed Everest use a helicopter?

Nepal: Nepal said on Tuesday it was investigating whether a Chinese woman, this season's sole climber of Mount Everest from the Nepalese side, used a helicopter to reach a high camp after a deadly avalanche last month washed away part of the route.

Using a helicopter would constitute a serious moral violation of tradition in climbing the world's highest peak. But Wang Jing, 40, who completed the climb last Friday, denied she had used the aircraft to advance up the mountain.
