My personal feeling is that beings able to travel thru zillions of light years probably would not crash like common Cesnas and would be able to reveal themselves, or not, in one form or another.
As for Bush, didn't he leave the country? Where is Cheny?
Some believe they are after Tom Cruz.(!)
Did you ever consider "they" might be after Bush/Cheny, rather than Bush/Cheny being after us?
That being said, I'd still love to see the photos of mile-long ships, or any purported craft, as that is fun stuff.
