Emergency apparatus in the form of a rescue box for air-lifting survivors from burning high-rise buildings; the rescue box has opposed full-width and full-height doors hinged at the bottom, which act as passenger loading ramps when open as when the rescue box is set down on the roof of a burning building and which on lifting by helicopters is safely held closed by lifting lines proportioned for sharing the load with other lines to the rescue box; each door has a smaller door in it hinged inward at the bottom to facilitate escape into the rescue box when positioned alongside burning buildings, as through windows in the buildings; aerodynamic stabilization for steadying the rescue box during transport and landing is provided by a tail extending from an end of the rescue box; special view limiting and cushioning features are also disclosed.
