Fire department pesonnel stand by as workers prepare two unstable cranes for implosion at the collapse site of the Hard Rock Hotel, which underwent a partial, major collapse while under construction last Sat., Oct., 12, in New Orleans, Saturday, Oct. 19, 2019. Authorities plan to blow up the two towering construction cranes that have become unstable at the site of the collapsed hotel. They hope to bring down the cranes with series of small controlled blasts just ahead of approaching tropical weather. The mayor has imposed a state of emergency to seize property and force people out if necessary. They hope to avoid more damage to gas and power lines and historic buildings. (AP Photo/Gerald Herbert)
