What type of UFO/UAP is this GLP?

Several months ago, I posted some of my photos from a series of events occurring in mid-2002 to early 2003 related to apparent ufo/uap aircraft. Since then, I obtained a decent video software program which allows for a frame-by-frame review of the VHS video tapes that I also have. Yesterday while reviewing a tape, I saw an event that is hard to explain, and I am bringing the four “snapshots” to the GLP community for review and analysis. I am hoping to generate some thoughtful comments about what I am to tell and show you.

The four photos below are screen captures from a VHS video tape recorded in June 2002 with a Sony video camera. My new software allows me to review the tapes at the speed they were recorded – 30 frames per second, and to take “snapshot photos” of any frame, up to 30 snapshots per second of film. The four photos here are sequential in time – each photo represents 1/30th of one second. Keep the brevity of this event in mind. The camera time stamp shows the same hour/minute/second, confirming that all four were taken within the same one second of time.

In the first photo, we see an object flying through the evening sky in eastern Washington. The object is traveling toward the camera and it looks stable. Then within 1/30th of a second, the object begins two violent maneuvers – each 1/30th of one second in length, and then again stabilize at 3/30ths of one second after the first photo. What in the world moves like this? I have considered the possibility that photos 2 and 3 were the result of camera vibration at the time of filming. But I have observed camera vibration in a few of my time-delay photos, and the movement here looks nothing like that. And second, what type of vibration would be so strong to cause the camera/tripod/table to shake like that but last only 1/15th of one second?

I have additional screen captures of this event which shows additional incredibly fast movements from this same aircraft, but want to start with these four. What kind of technology was I seeing 20 years ago? I wonder if the object in these four photos shows the flat forward-facing side of the TRB triangle craft?
