"Sleek as a swallow and swift as sound, a new type of bird is flying high in the sky. The bird was made by man, and man calls it the jet airplane. But the jet is like no other plane. It flies twice as high and twice as fast - and carries twice as many passengers - as the planes that man made just ten years ago. If you were traveling in a jet now, you would have covered four miles in the time that it took you to read this paragraph. The chances that you will travel in a jet some day soon are very good."
