The challenges with ultra short high altitude runways in Nepal was of course a challenge which demanded airmanship at a high level. First and foremost was the will and skill to fly safe. This included ability to pilot the Twin Otters close to and sometimes at the edge of their performance limits, but never beyond. Insight in high altitude mountain flying, local weather phenomena combined with the limitations of each STOL port. It has been too many accidents and I am confident that many could be avoided with stricter understanding, skills and discipline.
The Will and Skill to fly safely can never be overestimated.
