It is the purpose of this monograph to present a critical review of the ability of the engineering profession to anticipate the dynamic environment of a flight vehicle, to predict the vehicle response to this environment, and to simulate the expected environment in the laboratory.

The following paragraphs describe briefly the subject matter. In that sense they serve as an outline. Their primary purpose, however, is to make explicit the interconnecting ideas and logical relationships within the material to be covered.
