I saw part of one object 3 times over 2 minutes, reflecting sunlight. Seen from Dungeness Spit looking south toward Olympic Mtns.

Dungeness Spit is a five mile spit of land that ends at a light house. It was a warm, cloudless day with beautiful views of the Olympic Mountains to the south of me. Three of us hiked out to the lighthouse for lunch and were about half way back (heading west) when I saw the first object. I called out, "There's a UFO!" My friends (as well as others on the beach) looked to the vast sky where I was pointing. Almost immediately, I saw a smaller object to the right (west). After scanning the sky, we walked on. Within 2 minutes I saw a third small object to the left (east). No one saw them but me. I would estimate that they were flying somewhere above Sequim or south of Sequim. They did not appear to be as far away as the mountains.
I do not know whether I saw one object 3 times or three different objects. I believe that I was seeing only a part of the object(s) - and this part was reflecting sunlight. The first object was observed the longest - maybe for a full second. The others were just similar flashes.
The shape of the object was a 2 dimensional oval with the top cut straight off. Imagine cutting this shape out of a piece of paper. I saw it with its long side tilted about 30 degrees towards me. Immediately, it began rotating up. When it became flat, it disappeared. Just blue sky. Again, I believe I saw only a small part of a larger object (with the rest of it invisible or cloaked?). The part was reflecting the sunlight which is why it appeared flat.
I originally reported this to MUFON and was contacted by their investigator.
