The event took place – or will take place, depending on how you look at it – on April 5, 2063. That evening, a Vulcan survey ship, the T’Plana-Hath, landed in Bozeman, Montana, after tracking the warp signature of the Phoenix, a spacecraft that represented mankind’s first successful attempt at achieving warp drive.

And, of course, moments later on that same day, a robed Vulcan, flashing the split-fingered Vulcan salute, greeted Dr. Zefram Cochrane, creator of warp drive and pilot of the Phoenix. Thus, First Contact was made, setting in motion a chain of events that led to the formation of the United Federation of Planets. (Star Trek)
