The fact that the US Govt (even if it's a Donald Trump cockup,
but it might be a good cockup) is publicly acknowledging the
existence of UFOs (and accordingly, strongly implied
extraterrestrial presence on Earth) for the 1st time in human
history, is a significant step towards eventual disclosure
(there'll never be full disclosure, don't be naïve).

Are we alone in the universe? Government officials confirmed for
the first time this month that the U.S. Defense Department has been
trying to answer that question, according to the New York
Times.
Out of the defense department’s $600 billion budget, a very
well-hidden $22 million went to the Advanced Aviation Thread
Identification Program, an initiative that investigates reports of
"anomalous aerial vehicles," more colloquially known as UFOs.
The former director of the program, a military intelligence
official named Luis Elizondo, resigned in October and shared
previously classified videos of fighter jet pilots sighting
UFOs.
"There's a whole fleet of them!" one US military pilot can be
heard saying.
The video, taken from the cockpit camera, shows glowing objects
traveling at high speeds while rotating and includes audio of Navy
pilots struggling to process what they are seeing.
