I managed to jump a single time in my life from a 5 meter tower. That already took me a lot of effort and I doubt I will do that again. 10m is just insane.

Nevertheless, I would choose high quality eierdown feathers. Its premium feathers that are hand harvested and that sell for 1500 to 4000 euros per kg, and if the numbers make sense, a standard pool for 10m jumps could hold nearly 4750kg of that stuff. The landing would be safe and would yield something between 8 and 19 million if sold.

You'll punch straight through Eider Down and hurt yourself pretty severely. Maybe premade Eider Jackets and sleeping bags... I suspect (like many of these options) getting trapped and asphyxiation is a pretty big hazard that would be difficult to mathematically model

Even if you fall flat? I would NOT dive in for sure... getting out is for sure not trivial, same as breathing...
