Haven't heard:
(1) Let it wash away in a spillway flow
(2) Dig a hole and bury it
(3) Somehow lift itself out
(4) Use anti-grav pods
(5) Use a cloaking device
(6) Use invisible paint
I like the anti-grav pods. But if we had that tech we wouldn’t need cranes.
Take it apart and lift the pieces with another crane.
