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.
