Penang Malaysia. A tower crane fell 40 meters, landed on it's tower top, and yet the operator lived. Astounding. The way that appears from this picure, I would guess that we are lookin at a bolt failure between the tower and turntable. Corrosion is common on old cranes. Owners don't want to take the time or money to buy new bolts so they run them too long. I have an example of what is begining to be too long from Seattle. 35 years on the same bolt is too long.
