The 1939 New York World's Fair had something for everybody, including the certifiable.
A prime example is Raymond Loewy's take on intercontinental travel: the Rocketport. Need to get from New York to London in a hurry? The Queen Mary just isn't fast enough and the Concorde is sooo 20th century. What's the solution? How about getting getting yourself fired out of a rocket gun big enough to fit an ocean liner in its muzzle. You'll get to Piccadilly in record time, I suppose, though you'll probably find that the shampoo bottle in your luggage has broken and you've got Head and Shoulders all over your jammies.
