UFO's and extra-terrestrial life

[bongodriver]

But can we ignore the evidence of air, land and naval radar operators that have simultaneously tracked craft doing things and travelling speeds well beyond the envelope of any known aircraft? Why doesn't that count as evidence?
Is every single sighting (even by experienced pilots etc.) one of mistaken identity, tiredness or confusion?

radar traces are routinely recorded and can be saved in case of any significant event, why has no controller ever pulled the tapes on a claimed sighting? pilots are just people, we don't all think alike like robots, we are all as individual as the next person, so it is reasonable to assume 'some' pilots are inclined to believe in UFO's and magic fairies and will use their apparent social standing to prop up the credibility of their alleged sightings.

I for one don't believe the goverments of the world are capable of concealing any existence of ET's, if they really are visiting us then they are beyond the jurisdiction of our authorities, secret bases and installations are for nothing more than secret earthly research and development.

Arguments noted guys.

All I'm saying is that personally I choose to keep an open mind on the subject. That's all.
Hey, maybe 99.9% of what constitutes 'evidence' of UFO's existing is false and fake. But even if 0.1% seems to be genuine, then that to me is interesting.

Bongo - Apparently (and I say this with great caution) tapes have been pulled. Thing is, who gets to review them and decide if it's genuine or not?
