Everybody having heared about Lukla probably will not be too surprised about a plane crashing there, with the runway just 1500 ft long and one end leading directly into the mountain wall, giving zero space for any error: your first approach has to end in touch-dolwn, or you are dead meat - and eventually take parts of the village with you. The real miracle seems to be that there are just so rare accidents.

This FS-video (wait until 0'30") shows schematic what a tricky place it is. There are plenty of landing videos for Lukla at youtube as well.
