Clocked Aircraft could explain some UFO sightings

a lot of the time when ufos are seen its only equipment that can see it not the naked eye? so ive come to the conclusion that ufos are using some sort of clocking device or something like that to bend in with the sourrounding

I also think that some form of optical stealth would be used by UFOS.Heres a thread I started awhile ago talking about this subject. I personally think a alien race that made it all the way to earth would not ever been seen by humans eyes unless they wanted to be seen.

yeh i had a read through its all very intersting

Some reports even mention a way to "cloak" ufos by emitting signals to our brain that should say somthing like "No were not here - just go about your business human!"

Seriously, how many times have you not heard the story "then when we developed the negative there was a ufo in the picture, 100% positive it couldn�t be seen when the picture was taken"?
This would posibly explain it, as a camera would not be affected by "mind control emitters" (my own term).

However the technical cloaking theory is a LOT easier to accept.
But anything is worth considering.
