This video was requested via the Freedom of Information Act (FOIA) by John Greenewald, Jr. of The Black Vault. The FOIA Case number for reference is F-2018-00088.
The video was released in five, individual files. These have been unedited from their original form, but have been combined here for easier viewing. The slates in front of all five clips appear, and are marked by the “NRO Approved For Release May 2019” image.
The video was seen as a reference, in a declassified “Joint Inspection of the National Reconnaissance Office” which I received from the Department of Defense’s Office of the Inspector General. That document can be seen here.
