Released Summer 2012 - not known or reported about.
Witness statement: 'I know the film is genuine because I filmed it myself!
The interesting point about this film is that only saw object when reviewing film rushes- the object moved so fast it couldn't be seen by the naked eye.'
These things travel at speeds which most of the time we simply cannot perceive, and/or they operate in a manner in which their light spectrum is effectively invisible to our eyes.
