Some of those actually look convincing, but some don't. Nice find though.

Most, if not all, are known hoaxes.

Agreed and a few of them were CGI.

This video claims to have sounds made by UFOs::

Seems to me most people who have seen UFOs claim the UFOs are silent.

those are some really annoying sounds lol...it would be bad to have one of those ships as an everyday vehicle!
BUT there isnt only one way to make antigravity so i guess this is (IF IT IS REAL) how their ships sound.

Well, the Phoenix Lights video was not a hoax... but, alot of the other ones were. Especially the one where it was hovered over a swamp. That was so horribly made.

on the photos and sounds video, the picture with the ufo over a truck were proven hoaxes.. i remember seeing a documentry on it, the photographers wife said that that was the top of their trashcan with some other household stuff stuck on!! shame!!!

the clip with the orb lights making crop circles was fake as it was filmed south of England and the guy came out afterwards

and the clip with the sounds should never be played that was very anoying!!!!!!!!!!!!!!!!!!!!!!!!!!

yeah i agree, i put it on mute, it sounded like something out of a bad old horror movie!!
yeah i remember when they discovered the crop circles one was a hoax, the guy worked for a film makin company, and even had the edit data on their company files!

Flairs...proven.
