Helicopter rescue basket

A helicopter rescue basket is a basket suspended below a helicopter in order to rescue people from a fire or other disaster site.
Uses
There are two main types of helicopter baskets. The smaller, more common type is used by rescuers to lift a person up from ground or water into the helicopter. An early type that could scoop an unconscious person from the sea was the Sproule Net, invented by Lt Cdr John Sproule, RN, in 1956 which was used by British helicopter rescue units until the late 1970s
The second type is a new invention. This is a basket able to fit five people or more. It allows a large group of people to be rescued from a fire or other emergency site, without needing to load them into the helicopter itself. It enables the helicopter to load a large group without landing. The helicopter hovers over the site and rests the basket on the ground or other surface. Evacuees board, then are transported to a safe area.
