I think this is fundamentally impossible, win loads are powerfull enough to ouright warp and destroy giant ground based cranes like they were tissue paper if the operator makes a mistake, like lifting oart of a stadium roof in high wind. there are scary videos all over youtube. Those things and made of hige steel girders.

This is going to be a light, fragile airframe with much bigger 'sail' in the form of the airship - its the size of a stadium.

Nothing short of a rocket engine will be able to keep it in place.

The skin of a Boeing 747 is about 2mm thick. We’ve been hurling them at 600mph through storms for half a century at this point.

I don’t know for sure but i suspect the airframe of this concept is within reach of current tech.

The passenger planes have a tendency to break in half mid air if they are subject to sudden stress, turns, etc, like TU 144 did at a paris airshow.
