I can think of better ways to make a living than flying in Nepal.Cleaning the outside windows at the World Trade Center comes quickly to mind.
Ran out of airspeed, altitude and right rudder. Unless they find mechanical failure, this was pilot error, both pilots. The pilot not flying the approach should have been monitoring the airspeed, glideslope, power settings, configuration etc.
I prefer to think it was unrecoverable mechanical failure. I doubt this.
