"Berlin to New York in less than One Hour!" written by Hugo Gernsback and illustrated by Frank R. Paul in the November 1931 issue of Everyday Science and Mechanics. This proposed spaceship would reach an altitude 700 miles on its one hour trip from Berlin to New York. The article notes that "the tremendous acceleration of the flyer during the first few minutes makes things rather uncomfortable for the passengers." Artificial refrigeration would keep the passengers and ship from getting too hot on re-entry. A major problem to solve is the weight of the fuel required for the trip.

  • Deutsch : „Von Berlin nach New York in weniger als einer Stunde!“ geschrieben vom Hugo Gernsback und bebildert von Frank R. Paul im November 1931 in der Ausgabe von „Everyday Science and Mechanics“. Nach diesen Vorstellungen würde ein Raumschiff auf dieser Reise von Berlin nach New York City eine Höhe von 700 Meilen (1.127 Kilometer) erreichen. Dieser Artikel stellt fest, dass „die ernorme Beschleunigung des Flugkörpers während der ersten paar Minuten die Reise ziemlich unangenehm für die Passagiere macht“. Künstliche Kälte würde die Passagiere und das Schiff vor einer Überhitzung beim Wiedereintritt bewahren. Das Gewicht für den Treibstoff, welches für die Reise benötigt wird, ist ein weiteres großes Problem, was es zu lösen gilt.
