What is the difficulty make a jet preform at the altitude of everset, so that a vehicle could not be built with verticle lift engines enabling rescues off of the mountain?

Im not an aeronautical engineer, but jets perform at altitude at a reduced amount of thrust..there is less oxygen, thus less power is produced, but being that the air is thinner, the aircraft is able to maintain speed, although the stall threshold increases..the problem with going vertical, is you are not just trying to push an airplane through the air using a lift of a wing, but you are trying to overcome gravity..helicopters encounter the same issues at hovering at altitude. I think it might be possible..the JSF has an engine that produces about 40,000lbs of thrust..and a lift fan that enables VTOL capabilities...Use that technology in a rescue type of aircraft...and if you could find a flat enough spot to take advantage of ground effect..it might work..but thats a whole bunch of ifs..

Weather would be a large factor for any rescue vehicle.
And vertical jets sufficient to maintain altitude in a rescue craft would certainly raise havoc with the terrain below it - possibly causing more harm than good to anyone in the vicinity on the mountain.
