What goes up, must come down

Watch out for falling cranes, people.   This happened in front of my apartment building yesterday. Luckily no one was seriously injured:

They just erected that crane a few days ago.  Now, I’m not an engineer (although I did study architecture for a few years), but I’d walk by the crane every morning on my way to work and think to myself “how can that possibly stay up?”  Well, it looks like it didn’t for long.
