A Severe Strain on the Credulity

[KX4QC]

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.

-- New York Times Editorial, 1920

Maybe Goddard thought that rockets could still work in the vacuum of space?
It's easy to doubt expert opinions; a little learning is a dangerous thing.
