Why I Failed To Climb Mount Everest Without Oxygen!

My reflection on my attempt to summit Mount Everest this year without supplemental oxygen. Why did I fail, why did I have to turn around, what did I do wrong and what did I learn one month after the expedition?
How do I adapt in the future learning from these mistakes in order to becomea better mountaineer and be successful on my next expedition?
Will I continue to climb 8000ers and what is my next project gonna be like?
This is my attempt to summit Mount Everest solo withou oxygen in 2024.
After Annapurna I and Lhotse without oxygen, this would be my 3/3 8000er without the use of supplmentary oxygen!
In this video I will take you with me to the South Col, Everest Camp 4, the Geneva Spur, Lhotse Camp 4, across the Yellow Band down to Camp 3 in the Lhotse Face, back to Everest Basecamp, down to Lukla and with the Helicopter to Kathmandu and finally back home to Europe.
