As a method of sending a missile to the higher, and even to the highest
parts of the earth's atmospheric envelope, Professor Goddard's rocket is a
practicable and therefore promising device. It is when one considers the
multiple-charge rocket as a traveler to the moon that one begins to doubt
... for after the rocket quits our air and really starts on its journey, its
flight would be neither accelerated nor maintained by the explosion of the
charges it then might have left. Professor Goddard, with his "chair" in
Clark College and countenancing of the Smithsonian Institution, does not
know the relation of action to re-action, and of the need to have something
better than a vacuum against which to react ... Of course he only seems to
lack the knowledge ladled out daily in high schools.
