Whenever you listen to someone describe something in the sky they can’t explain, it is not too long before the phrase “I know what I saw” crops up. So when someone produces a documentary about unexplained aerial phenomena, titling it “I know what I saw” doesn’t come as a surprise.
It is a phrase I used myself when I saw something I couldn’t explain off the coast of East Yorkshire.
The video above is a documentary that avoids sensationalising events and instead goes to eye-witnesses.
Now, Police will tell you that eye-witnesses can be remarkably unrealiable, so the documentary maker also includes testimony from those behind the scenes who actually investigate the reports.
