There has definitely been a release of information - say, since the 90s?
in many different 'unexplained' areas.
Underwater finds, say of ancient advanced civilisations,
of 'UFO' evidence - and others.
In reading about Nazi Flying Saucers, these are of a particular type -
so they can be identified in photographs. What information there is
available about them, suggests they are in 'isolation' and their
influence/etc is somewhat static.
Perhaps their activity has declined by now, due to their craft being
old and non-functioning now?

There is a lot of evidence that the Nazi's had flying saucers.  They
were believed to have 'death ray' weapons onboard.  There is
speculation that they were unmanned robotic electromagnetic aircraft.
That 'Foo Fighters', without obvious means of propulsion, buzzed our
planes in WWII is fact.

What these 'Foo Fighters' were is not known for certain, however.

Later, in the 50's, when antigravity was being talked about and Project
Winterhaven was out in the open, the main problem was the amount of
weight that the antigravity vehicles could lift.  The USAF wanted
vehicles that could lift many thousands of pounds of bombs.

All of the above is 50+ years ago.  Today the technology, if it exists,
must be highly classified because nothing is heard about it from any
official source.

That it was developed in the 50's seems certain based on many articles
and announcements made at that time.  Whether it was the 'practical'
propulsion system that the USAF wanted is unknown, but a breakthrough
in the lifting power of antigravity was the last 'document' coming from
the UK in 1956.

General Electric was the company most involved in it, based on the 50's
documents.  A Google search on 'antigravity+GE' will provide a wealth
of information.
