The article further states that a true black program may be unlikely to fly during daylight (crash time @6pm local), but some indeed did.
I tend to lean foreign or black. Seems too early for a B-21 technology demonstrator or prototype. A F-117 could be explained as a loss during flyable storage validation. Black and Foreign tend to stay pretty quiet. And yes as Dave68 suggests, there have likely been several other programs since Bird of Prey.
