and behind the scenes at the recording studio where zack bowman made his time album ahead of it closing down >>> after an exhausting night emergency crews in india are continuing effort to find survivors trapped underneath a collapsed flyover. 21 people are confirmed dead in calcutta, but the final death toll could be higher. it's feared as many as 150 could be trapped. a 100 meter section collapsed and fell on to a busy road. we were at the scene overnight. >> what's happening behind me is that heavy machinery - diggers, are trying to break through a slap of the fly over that fell on to the ground. rescue workers believe there are several vehicles trapped under the ground. it is a very congested area. the flyover is built in between building, and the end touches the walls or the windows of residential blocks, and it slowed down the rescue effort. >> before the ambulance arrived we were here at the location, and we were the ones that rescued the people. the government didn't pay attention. >> construction was delayed. they were under pressure to complete it. that was the deadline. many
