Houston residents left stranded on a rooftop due to floods caused by Hurricane Harvey were rescued by a US Coast Guard helicopter, as shown in footage released on Monday. A crew member winches down from the hovering helicopter to the awaiting residents. One by one they pull up the citizens, some of whom held their pet dogs in their arms. Houston's emergency services have received nearly 6... Еще,000 calls for rescue. The coast guard said they have rescued some 1,200 people, 200 of which were done by using helicopters.
