At the dawn of long-distance air travel only the very brave dared to cross something as vast as the Atlantic Ocean. If crisscrossing the globe by air was going to come to the masses, some people believed it would have to be helped along by some new innovations—like these artificial islands of the future, courtesy of 1927.
By the late 1920s, men like Charles Lindbergh, Clarence Chamberlin and Richard Byrd had crossed the Atlantic in that daredevil's pursuit of glory. But air travel for John and Jane Q. Public wasn't ready for primetime. Gimmicks like in-flight movies may have been taking off in that decade, but crossing giant bodies of water was still considered very dangerous thanks to the limited fuel and weight capacity of aircraft at the time.
