essentially one of the workers as you just heard officials describe said that the crane was bringing up heavy concrete that was needing to be poured on this high-rise as they continue construction when they believe there was some sort of mechanical fire. this person describes it to me as they saw the cab of the crane start to smoke and actually fill up with smoke. frank, you can go up and show where that crane did collapse. they said the cab started to smoke, filled up with smoke and he said once he saw the crane operator evacuate that cab, that s when he knew it was not a good sign. so he said that s when the building started to quickly evacuate of all of those workers who are now all standing on the streets here around me. one of the workers described to me that actually as they were trying to escape that building, they could feel the rumble of that crane swinging, as you see in that dramatic video, hitting that opposite side building and then eventually collapsing. i was told again
