One of the most interesting things I heard from Jill Tarter that was very interesting was that they incorrectly thought they found extraterrestrial intelligence on two separate occasions but that on both occasions they where man-made aircrafts.

I also find this very interesting, you'd think we'd have an idea of other man-made aircrafts so that we wouldn't make this mistake. Maybe its just our desire to find extraterrestrial intelligence that drives us to look for it in things that aren't extraterrestrial. This also reminds me of all the recent news on UFOs and the fact that the government is now confirming they exist. It really makes you question what this universe truly consists of and again it caters to our desire to find life outside of our own.
