Electrical Experimenter (07:09) January 1920

Hugo Gernsback, editor

"Henry Woodhouse, the well-known aviation expert, recently gave out a report that there had been plans disclosed in Chicago for a radically new type of flying craft, to be propelled by electricity entirely, and therefore to be of such great power and efficiency as to be able to make flight around the world. The airplane is also credited with being capable of carrying from 75 to 100 passengers, and the wings are to have a spread of 240 feet, while the airship itself is 180 feet in length."
This is the January 1920 issue of Electrical Experimenter. The cover story is “First Wingless Airplane,” introducing the helicopter. Another article features a model helicopter design. Other articles include whether an electric airplane is feasible, learning telegraphy at school, the radio compass, and Einstein’s theory of relativity.
