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.

Should such a time-slowed condition be engineered in an advanced aerospace application, an individual who has spent time within such a temporally modified field would, when returned to the normal environment, find that more time had passed than could be experientially accounted for. Conversely, for an engineered spacetime associated with an advanced aerospace craft in which ‘R >1, time flow within the altered spacetime region would appear sped up to an external observer, while to an internal observer external time flow would appear to be in slow motion. A corollary would be that within the spacetime-altered region, normal environmental sounds from outside the region might cease to be registered, since external sounds could under these conditions redshift below the auditory range. An additional implication of time speedup within the frame of an exotic craft technology is that its flightpath that might seem precipitous from an external viewpoint (for example, sudden acceleration or deceleration) would be experienced as much less so by the craft's occupants. From the occupants' viewpoint, observing the external environment to be in relative slow motion, it would not be surprising to consider that one's relatively modest changes in motion would appear abrupt to an external observer. Based on the second entry in Table 1 (frequency), yet another implication of an accelerated timeframe due to craft-associated metric engineering that leads to ig00 >1, frequencies associated with the craft would for a remote observer appear to be blueshifted. Corollary to observation of such a craft is the possibility that there would be a brightening of luminosity due to the heat spectrum blueshifting up into the visible portion of the spectrum (see Figure 1). infrared Frequency w A 1.
