I have shown various images of either rescues, or, persons who perform these rescue operations. However, sometimes, a rescue operation may take place rather quickly and quietly. A few weeks ago, some workers were putting the finishing touches on the Trump Plaza hotel when one of the sky buckets malfunctioned, stranding some workers about four stories on the outside of the  building with no obvious means of escape. This was not a problem as there was another such vehicle in place working on an another section  of the same building, near by. The working vehicle simple approached the defective one and an impromptu rescue mission to rescue the stranded workers was taking place.
