Aliens with triangle-shaped U.F.O

Unidentified aerial phenomena come in various forms, although the prototypical form of "dish" seems to remain the most common. However, since the early 90s, the UFO sightings of a triangular shape multiply on five continents, to imitate the increased presence of reconnaissance aircraft or stealth bomber technology, such as the F-117 or B-2, in our skies.

While the public is familiar with this type of gear through the media, observations describing triangular UFOs continue to flood in posing a real conundrum: if it is not misidentification of devices known to witnesses, are we facing new technologies of hidden knowledge or an armada of vessels belonging to a very powerful "foreign" or aliens?
