Karson Kammerzell had a Triangle UFO sighting on the night of the Tic Tac. He was on the deck of the Princton and saw lights in the form of a
triangle, which suggest that he did not see a Tic Tac craft but a different variety of craft ~ a Triangle. This of course could mean that the 2 types
of UFO’s were WORKING TOGETHER somehow in the same air space. As in the Navy had their Carriers and Cruisers at that location and the air fleet had
their Triangles and Tic Tacs there.
So we might not be talking about a completely different “species” of UFO. Like people in the past seeing saucers coming out of cigars in the sky,
the triangles and tics might be working together.
....if you made a craft out of Metamaterials and fired it up using Pais/Puthoffs PV model where the outer layers are excited into manifesting weird
permeability and permittivity values....it might appear as different "shapes" depending upon the incident angle of the observer/settings on the
dial.
...which reminds me of Fouches TR3B and the ability to appear as a Delta or Cylinder - co-coincidently from the same "lecture" where he introduced
Quasi Crystals AKA Metamaterials into UFO Lore.
