@cbsmiami: Four people in Brickell escaped serious injuries on Monday morning after an 85-foot drilling rig collapsed and crushed vehicles and a construction container, Miami officials said. When crews arrived, they said they found that the drilling rig fell onto Brickell Bay Drive, crushing three vehicles, including one that was on fire, and a construction container, trapping workers inside. Fire officials said that the Miami Technical Rescue Team immediately began a "complex rescue operation" to save those who were trapped while first responders were also working to extinguish a fire that broke out in a white SUV when it was hit by the collapsing rig. A search inside was also conducted to make sure no one was trapped or injured. The construction site was building the new global headquarters for billionaire Ken Griffin's hedge fund, Citadel.
