On Tuesday, one person died and another was injured after two helicopters collided and crashed while trying to land in Nepal's Everest region.
These helicopters, which belonged to the private companies "Fishtail Air" and "Dynasty Air", carried passengers and rescued cargo respectively.
In Nepal, helicopters are widely used to transport tourists, climbers and supplies, as well as for emergency evacuation operations; But the roughness of the land and the rapid changes in the weather in this country make flying particularly dangerous.
