CSETI (The Center for the Study of Extraterrestrial Intelligence) has in the past 18 months succeeded in intentionally establishing contact with extraterrestrial spacecraft, on two occasions at very close range, and with multiple witnesses present.

It's been by turns frustrating and fascinating and wonderful beyond imagination. If what I suspect is true, it's one of the most important milestones in human history to acknowledge that we are not alone in the universe.

There are hundreds of credible reports, many with multiple witnesses, of humanoids in association with landed spacecraft.

There are more than 3500 military and commercial aircraft pilot reports of encounters worldwide; many cases have corroborating radar documentation and multiple witnesses both on the ground and in the air.
