A discussion of current trends in aerospace computation. Total U.S. computing power is expected to increase by a factor of 1000 in the next ten years. While computers are becoming faster and more efficient, computer software remains a handicraft industry, custom-made and too frequently idiosyncratic. Programs often subtly distort the projects they are intended to assist. Conversion from one machine to another is time-consuming. Programmers should strive for interchangeability, using machine-independent programming languages and modular units. Continuous reexamination of goals is necessary.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
