This is an unclassified Defense Intelligence Reference Document (DIA-08-1003-015), dated 29 March 2010. The Defense Intelligence Agency prepared it under the Advanced Aerospace Weapon System Applications (AAWSA) Program, and Rep. Burchett entered it into the House committee record. The paper uses a general relativity metric tensor approach to look at how engineering spacetime might enable propulsion, including warp drives, apparent superluminal travel, reduced effective mass and antigravity. It finds these ideas consistent with physics but far beyond present engineering capability.
