EXHIBIT "A"

Project Sign Study Requirements

The possibility that some of the unidentified aerial objects that have been reported both in the United States and in foreign lands may have been experimental spaceships, or test vehicles for the purpose of assisting in the development of spaceships, has been given consideration by this Command.

If such craft actually have been sighted, it is believed more likely that they represent the effort of a foreign nation, rather than a product from beyond the Earth.

Present world knowledge, techniques and resources are probably adequate to meet the requirements for spaceship construction, or at least to establish the preliminary experimental foundation for such an accomplishment in the near future.

In any case, the design and performance parameters of the craft would necessarily be in conformance and consistent with the established principles of our sciences.

To assist in the collection of information, relating to unidentified aerial objects that may possibly represent spaceships or spaceship test vehicles, and to assist in the analysis and evaluation of such reported craft, technical information that includes the distinguishing design and performance parameters for spaceships is considered necessary.

While such information is contained outright, or implicitly, in the series of Rand Project reports, it would be of much value to this Command to have a list of the special design and performance characteristics that are believed to distinguish spaceships, together with any further scientific clues that might assist in their detection and identification, prepared by Rand scientific personnel.
