I believe there are allot of conspiracies being hushed
other than UFOS. I don’t think we will ever know the real truth.

The world’s government’s deny any existence of UFOS.
Would this just be to prevent panic and maybe to protect organized religion.

On the 24th of June 1947 an experienced air pilot called Kenneth Arnold,
was flying an air craft through the cascade mountains in Washington state,
when he spotted a flight of nine cres-cent-shaped aircraft flying in formation
in the vicinity of Mount Rainer. The aircraft appeared to dip or skip through the air.
News of the sighting soon hit the news afterwards, who reported the unidentified
objects as having travelled a phenomenal speeds impossible for any
known aircraft to be able to achieve. There followed a wave of UFO sightings
across the US and general panic about whether alien invaders or
 ( perhaps worse) the Russians were violating US airspace.
 Kenneth Arnold’s sighting is regarded as a classic UFO encounter,
with a robust and reliable civilian aviator providing the most credible witnesses.
