Yes and No.
I think that alot of earlier UFO repoorts were actually gov. projects,
perhaps using EMF manipulation.
For such manipulation, early models would work well being disc shape,
since they'd be using with early versions of the technology.
The triangle shape, assuming that it uses EMF, could use an advanced
form with a generator at each tip.
But I honestly think that it's likely that only about .8% of UFO cases are
true UFOs, that being no one here (on Earth) know what they are,
or where they came from.
Oh, and EMF stands for Electro Magentic Field.
