Plane Crashes and Disasters

There are several stories of airplane crashes flying from Kathmandu, Nepal to Lukla the small village where most treks start up some of the most famous mountains in the world. Just google Kathmandu plane crashes. It's not a very comforting sight. One story said that the total number of people killed in eight aviation disasters in the last six years has now risen to 114. Here is that story.
Here is a bit from a BBC news story. 
British mountaineer Alan Hinkes told the BBC he had taken the flight from Kathmandu to Lukla many times and that problems usually occurred at the Lukla end.
"The landing strip in Lukla is a bit like an aircraft carrier with a mountain at the end of it, with a 1,000ft drop at the end of the runway. Normally crashes happen at that end," he said.
He added: "It is not the safest place to fly, I must admit, but it is what you have to do to get into the mountains."
Aviation accidents involving small aircraft are not uncommon in mountainous Nepal.
In May, 15 people were killed when a plane crashed trying to land at an airport in the north of the country.
And in September 2011, 19 people were killed when a Buddha Air plane crashed during a flight to view Mount Everest.
Here is a link to the rest of the article. It also has a video that describes the crash.

Plan crashes aren't the only disaster to worry about. Ama dablam has many reported incidences many from Avalanches. In 2006, a large Avalanche happened which killed 6 people.  Camp 3 completely fell off the mountain side. Rescue Helicopters have also crashes while attempting to save climbers.
