Six months after a Sita Air Dornier suffered an undercarriage failure while landing at Lukla airport, (pictured) a Gorkha Airlines Dornier skidded off the runway on Thursday morning. None of the eight Nepali passengers and three crew were hurt. Lukla\'s famous inclined runway was tarmaced three years ago and has since seen a big jump in landings and takeoffs. There have been eight mishaps here in the past 10 years, although none of them resulted in fatalities. Pilots regard landing in Lukla as one of the most challenging in Nepal because of the terrain and weather.
