Watch the Big Triangles

[A continuation of sorts of 'Would They Talk to Us'].

The most compelling evidence that at least one group of ETs intend that we know of their presence, and by implication, that they intend the possibility of Contact, is the behavior of the large triangles.

Two of the events are the Hudson Valley and Belgium sightings, decades ago. Both involved sightings by many witnesses over many days and longer. The Belgium case involved interaction with military aircraft, and amazingly (by the standards of the US Air Force), the Belgium military openly acknowledged the events.

The next (?) major event was Phoenix, witnessed by hundreds of people. Initially ridiculed by the governor of the state, a former Air Force Officer, years later it was confirmed when the governor acknowledged he had in fact personally observed a large triangle, which was (to him) obviously 'not of this earth'. At the risk of stating the blindingly obvious, the appearance occurred when many people were outdoors, looking at the sky to see the Hale-Bopp comet; any ET race would have understood that this would be an ideal time to demonstrate their presence.

Finally, the Stephenville event was not simply an obvious demonstration of intent that humans would know of the ET presence, but may have been a message to the U.S. Government, since the flight path apparently ended near or at the restricted airspace of the President's ranch. While there's no publicly available 'proof' to support this speculation, perhaps the U.S. Government got the message:

{We can do this in 'broad daylight', when the President is at the Ranch, when lots of reporters with lots of cameras are watching. If you continue this policy--and if you continue to believe that the greatest threat to the future of humankind is the truth--too bad. Sooner or later the truth will be known, and if you don't deal with issue, at some point we may--and if you aren't prepared for it, you have only yourselves to blame.}

Was a revised version of a U.S.G. 'UFO Preparedness' plan distributed more widely, at least partly as a result of this event?
