14 Mega Machines That Were Built… Then Immediately Abandoned

What unites them is not failure of engineering, but failure of timing. These projects reveal moments when ambition outran practicality, and when history turned faster than steel, reactors, or concrete could keep up. Each of these machines briefly stood at the edge of what was possible, then was left behind almost as soon as it was built.
