Call it a "Rescue Sled"........Really light and really cheap.
With that being said, not even our military leaves our injured and deceased behind.
There is no reason why a climbing party can't abort their self obsessed mission to help a fellow walker in distress and take him/her back down the mountain.
The fact that they don't, they should be charged with accessory to murder or some other such charge for not helping the dying individual.......
Do you actually find it noble that a climbing party ignores the distress of a fellow climber and instead of helping him/her back down the mountain, leaves him/her behind just so you can achieve your own personal goal of climbing to the summit of Everest?
Is that what your accepted view of humanity is all about?
And please, don't even try to cite all the legal documents they would have to sign off on in order to contract with these idiot outfitters...........
