Transporting a Rhino by helicopter believe it or not is the safest way to move one of these guys out of the wilderness. The black rhino is critically endangered and just yesterday one of the four black rhino sub-species was officially declared extinct. The South-African WWF department airlifted 19 of the critically endangered animals to the nearest road where trucks were waiting to transport them another 1,500 miles. The objective is to spread the populations, and thus reduce the chance on extinction. This video has some spectacular images of these rhinos being lifted into the air.
