No extraterrestrial craft -- UFO, flying saucer, whatever -- would have a symbol on it.
My point in re-asserting the images is that I plan an upcoming piece on why visitors from outer space could not -- that is, could not! -- have symbols on any alleged craft they flew here.
The thesis is based on the human history of writing, which you can follow by first reading this article from Wikipedia:
This means that Lonnie Zamora's craft could not have been an extraterrestrial craft, a point I've made many times previously.
(The supposed symbol -- no matter which one is the real one -- is the smoking gun that defuses any argument for Socorro being an alien event.)
