"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools."

"Correction: It is now definitely established that a rocket can function in a vacuum. The 'Times' regrets the error."
NY Times, July 1969.
