Please, I mean no disrespect to anybody in saying this, but something of this nature was an accident waiting to happen at Lukla. One could compare this airfield with Courchevel in France - without wishing to speculate, there is a certain pressure regarding runways of this length to have your mainwheels down and brakes applied as soon as possible - having watched a few videos of landings at these two airfields, it's surprising that somebody hasn't 'caught their mainwheels on the edge' before.
Then again, we all know the risks associated with aviation, and we shouldn't feel too sorry because unfortunately these things happen and in the grand scheme of things is simply the price to pay for the furtherance of mankind's exploration of the world we live in.
All the best, Jack.
