AERONAUTICS: Roof Landing

Intelligent is a device for planes to land on roofs, ships and similar small areas, described last week by R. James Gibbons, Brooklyn construction engineer and a member of the Guggenheim School of Aeronautics' advisory board.

It consists of a platform 210 x 60 ft. which turns on a swivel base 40 ft. in diameter to keep the length parallel with the direction of the wind. This swiveling is essential because planes can properly land or take off only against the wind. The platform also tilts up or down. The departing plane can coast down it; the arriving plane must roll up, constantly losing speed until it stops. Spring cables along the platform also retard the speed of the landing plane.
