Tim Burchett officially entered a document into the record during the last Congressional hearing titled Advanced Space Propulsion Based on Vacuum (Spacetime Metric) Engineering

During the last congressional hearing on UAP Congressman Tim Burchett officially entered a document into the record titled Advanced Space Propulsion Based on Vacuum (Spacetime Metric) Engineering.

Here is a timestamped link to the hearing where he does this.

If you are unaware this is one of the 37 Defense Intelligence Report Documents (DIRDs) created under the Advanced Aerospace Weapons Systems Applications Program (AAWSAP) that was uncovered by The NY Times. I have made a subreddit that gives access to all 37 documents if you wish to see them for yourself.

There are actually at least 5 DIRDs that focus on the subject of space time metric engineering. I have read all of them and written a layman report of what they are saying if you would like to read it for yourself. Below is a link to read it for free on my medium page.

In my exploration of the subject matter I discover that Hal Puthoff and Eric Davis have a very similar paper in which they recommend a modified design of previous work be tested to map negative energy density and even states that it could be assembled in an array for surveillance and detection of anomalous aerospace platforms.
