okay, I did @ggsimm's wire-tie thing because that's the standard now right?

NEW: Mysterious black triangles were spotted ripping through the air, traveling 1,800 mph over secret US military bases this past year, according to the Pentagon. According to the new government files, the triangles were spotted at least three different times. Agents say they were working at a surveillance station in an undisclosed mountain range when they saw the black triangle coming over the horizon. "We estimated the object’s wingspan at approximately nine to 15 feet, its depth at six to nine feet, and its thickness at one to two feet," they said to the FBI. According to the report, the triangles made no sound, had no exhaust, and showed a consistent heat signal when scanned by their thermal device, meaning it didn't register hotter anywhere as an engine would. "The exterior presented as a [seamless], featureless surface lacking any discernible structural discontinuities, propulsive apertures, intake structures, aerodynamic control effectors, or cockpit features," a memo said. Government officials say the objects were not American technology. The latest UFO file dump included the following sketches.
