Something else this photo shows very clearly.

The steel columns being blown out of the building are about half the length they are supposed to be. You are able to see the cut pieces side by side with the pieces breaking off near the building. Another observation is the cut pieces are shinny, compared to the uncut pieces which have your typical weathered steel appearance.

If you wanted to make a rusty piece of steel shinny, sand blasting would probably be your best bet. Using compressed air, you cause sand to move at high velocities against the steel, which chips away the rust.

There are three very interesting things to see in the photo: 1. A BUNCH of steel columns chopped in half. 2. Whatever chopped the columns blasted them clean in the process. 3. The cut steel columns have been propelled away from the building at a velocity considerably higher than that of the full length rusty columns that have simply broken loose.
