Seven Life-Threatening Building Failures

Parts of Philadelphia looked like a war zone after a vacant building being demolished collapsed onto a thrift store in 2013, killing six people and trapping more than a dozen under rubble.

The building collapsed onto the Salvation Army Thrift Store at 22^nd and Market Street with an ominous rumble, witnesses told CNN. A crane operator on the scene was later charged with involuntary manslaughter for his recklessness.
