WHAT the metropolitan skyport of tomorrow may look like, as conceived by Nicholas DeSantis, New York commercial artist, is shown in the illustration below. His remarkable proposal, embodied in a model that he has completed after five years' study of the project, calls for a 200-story building capped by an airplane field eight city blocks long and three blocks wide.

DEFYING the force of gravity, an aluminum bowl that is part of a novel device known as an "electromagnetic levitator" fascinates crowds at the New York World's Fair by floating in air with no visible means of support.

BILLBOARD blimps, carrying" flashing neon signs through the night sky above big cities, form the latest innovation in spectacular advertising. The aerial electric signs, developed and patented by Goodyear Rubber Co. experts, spell out sentences a word at a time like many of the big displays on New York's Great White Way. Ten lighting units, each approximately six feet high and four feet wide and formed of a maze of curving and zigzag neon tubes, are attached to the side of the semirigid dirigible before the take-off. An ingenious hooking arrangement permits them to be attached or removed in a few minutes. Each unit is capable of producing any number or any letter of the alphabet. During the flight, an automatic mechar nism makes the proper contacts to spell out the desired words on the side of the blimp. Perforated tape, similar to that used in player pianos, runs through the switching mechanism, the perforations tripping mechanical fingers to make the electrical connections. The sign remains the same until the next series of perforations is encountered, flashing on another series of letters.
