Astronomer spots Triangle with white inlaid lights passing silently at low altitudeIn a a very dark area where there is little to no light pollution. A triangle shape passed flat overhead a few degrees to the east. It was heading in a northwest direction, then swiftly made a change to the northeast without banking.The craft was totally silent, it moved as if it were a glider. Unlike most aircraft you see, its movement was distinct in that its movement seemed so effortless - (there was no loss of speed during its turn, no change in altitude, no roll, banking or any of the other traditional characteristics of powered flight.) Underneath it had several dull, faint glowing white lights that appeared to be inlaid on the bottom and illuminated the outline of the underbelly.I compared what I saw afterwards to several online videos of F117's and B2's in night flight. It did not resemble either.
