My sincere condolences to all concerned.
Everyone is so right to say this accident is a tragedy, it is.
Does anyone know why two obviously professional pilots would not know there is 17000 foot mountain on the route they were going to fly, or if they did, plan accordingly, or that they intended to land on an airstrip 3200 feet long at an elevation of 3300 feet where daily temperatures now are probably at least in the mid to high twenties in an aircraft such as a Metro with a good load in it, and expect to safely take off from the same airstrip?
