What the document records

The Defense Advanced Research Project Agency (DARPA) oversaw the development of HAVE Blue in the mid-1970s, which was the first practical, combat-stealth aircraft. HAVE Blue completed its first test flight in 1977, leading to the F-117A Nighthawk and TACIT Blue aircraft.

Type of case

Status

AARO designates unresolved cases as those for which the agency has not concluded the events were anomalous, has not concluded that they were conventional, and has not ruled out either possibility. Conventional candidates for sightings of recent periods include commercial drones, classified test platforms, satellite re-entry, balloon traffic, atmospheric optical phenomena, and astronomical objects.
