The assumption on shuttle launching of commercial satellite payloads is modified to reflect both the near-term shuttle program and manifest and the longer-term intent expressed in the Presioent's statement. Early in its deliberations, the ad hoc panel found that it had to make an assumption regarding whether the national intent was to have a sustained manned spacetlight program -- one in which manned flight was a regular and continuing occurrence year in and year out -- or to treat the shuttle fleet as a declining resource (Like the Apollo)

The number of schedulable Orbiters is fewer than the inventory because of a number of fundamental factors, some common with * The statement by the President, dated August 15, 1986, precludes continuing launch of commercial satellites by space shuttle.

This has necessitated cannibalization to keep the fleet flying and has lengthened the turnaround interval for individual Orbiters. In this report the panel attempted to estimate sustainable flight rates based on certain conditions, e.g., adequate spares, logistics, and all the facilities needed for turnaround and training.

tend ~ r ~ rid demand will always tend to come into balance. As launches using shuttles resume, there will be a buildup phase before reaching a sustainable flight rate.
