The Danish climber Søren Ledet stays on the mountain and as soon as the weather window allows he begin his attempt to the summit.

It appears from their website that the expedition carries their own equipment, but that they wish to use artificial oxygen - O2 above C3
A shame because the expedition looks strong and not “just” bought a seat on a commercial expedition ... like most other Danish ascents of Everest.
Once again we can’t hope for a climb without the use of artificial oxygen.
Have a look at their website: http://www.sorenledet.com.au/wp/
