Not really a training exercise...it was the pilot’s annual “NVG check ride”.
“...PAT25 originated from Davison Army Airfield (DAA), Fort Belvoir, Virginia, at 1845 EST on a visual flight rules (VFR) flight plan for the pilot’s annual standardization evaluation with the use of night vision goggles. Night visual meteorological conditions prevailed in the area of DCA at the time of the accident.”

Check rides are training. I’d have to give her a down.
