The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
Driving northwest from tri cities to yakima observed an extremely bright light in the distance. we thought it was a really large plane that was flying really low. stopped in grandview, got out of the car and the object flew straight over us. we observed a very large low flying craft with three stationary white lights in a triangle formation with one red blinking light in the center. it appeared to be very large, low flying and made no noise, completely silent. it seemed to move smoothly in a straight line.
