The reality of polymorphic, morphing, dynamic geometry anomalous flying objects had been known since the 1940’s, see Meade Layne publications of that time for example.
But the so called Ufologists had been trying very hard to push for a rigid vision of these manifestations, for them mechanical rigid artifacts are the “real UFOs” that is a very precise reflection of their rigid mentality.
Almost all our concepts of reality are based explicitly or implicity in the constancy of this reality, not surprising claims of objects with dynamic geometry challenge our more deeply rooted conceptions and the reaction to these claims are mostly irrational.
But there is really an overwhelming amount of consistent footage showing the reality of anomalous objects with dynamic geometry, this very fact have dramatic implications: since objects can have variable geometry then the particular shape that they may have in a particular instant is really irrelevant, also not particular shape is more relevant than any other.
This implies inmediately that the relevance given socially to “flying saucers” is artificial. To determine if an object is anomalous more detailed analysis is needed beyond the general shape that the given object may have.
