Personally, I think the thing that is going to revolutionize SAR is drone technology.
I'm thinking of a recovery that took place in one of the couloirs of the needles, that was very dangerous to rap. It could have been up or down flown in about a minute, with no risk at all.
With the current episode, all the likely fall areas could have been carefully searched in a day by one person, with no risk.
One might say that drones would be that much more additional weight, but if it replaced a bunch of climbing gear for exploration.....
