1. The experienced designers and analysts who learned from the successes and failures of the 1960s and 1970s are leaving the industry as a result of retirement and downsizing; thus much of this corporate memory and experience has the potential to be lost.2In addition, many of the younger engineers who have experience with the modern computational methods do not have experience in evaluating the accuracy of the flow physics provided by the advanced computational fluid dynamics (CFD) methods. Without the necessary mix of talent and experience, the new companies may find it difficult or impossible to build a launch vehicleabletoperform themissions needed. One possible result is a number of new vehicles which simply cannot carry out the launch capabilities promised. An even worse result is a repeat of past failures with the associated increased costs and lost confidence in the new vehicles. This latter result is not only bad for the company in question, it is bad for the launch industry as awhole.
