Around 2002-2003, I would occasionally see them fly by my apartment. They stood out right away because,they had no tail numbers. What was really
peculiar was that they were not American aircraft. I am prior service and I am somewhat familiar with military aircraft so, I recognized them as
British Gazelles. They flew by really close and made a lighting speed landing at the private airport in Newberg, Oregon then continued south. If I had
to guess, they were heading to Evergreen aviation in Mcminnville, Oregon where, this company has been known to contract with the Government for
C.I.A. and other low-key ops. I, too, believe there might have been something going on due to the fact that it was in the middle of summer on a bright
sunny day. It probably explains why they were in such a hurry before someone could get a good look at them.
To answer your question, no- I don't think you have anything to worry about. Who knows what they are really up to? Besides, I have been on
training missions, working with special forces; if they were interested in you, I would not have read your post.
