4 Orange Orbs in the sky the size of large blimps in Mukilteo, WA.I was in Mukilteo, WA on the night of Friday August 18th, 2012, near the ferry on the waterfront. It was approximately ½ hour before dark, the end of dusk, with my back to the water I looked up in the sky to see an odd occurrence.Knowing Boeing field was directly east of my location I was used to seeing airplanes fly overhead. I am very aware what they look like in the sky, the sounds they make and which colors their lights put off and how much light each light may glow. I was very confused to see bright orange orbs in the sky (school bus orange) about as high as a small aircraft would fly above the ground. I immediately thought it was in fact an airplane however there was no sound and the lights were not the lights on the wing because they were too bright and too far away from each other, as well as too large (the size of large blimps). I also was alarmed because if they were two different aircrafts then they were flying too close. I was very confused.I noticed 3 at first in the shape of an upside down V with the left point extended farther than the two other trailing points. Then they slowed down and waited for the fourth point to join them that created a diamond shape in the sky and turned sharply and slowly as if not afraid to be seen and headed east toward Boeing field, then over the mountains. We were able to watch them for a very long time; we visually lost them at dark.I originally thought they could have been Chinese lanterns, after the small airplane idea did not make sense, but there is NO WAY the lanterns could have burned this bright and been this large. I have lit the lanterns before here in Washington and in Hawaii so I know what they look like close and far away.On a side note: the radio station 92.9FM that I normally listen too in clarity would not come through that night on the radio I was listening on all night and had listened to 92.9 on it previously. I have never called or documented any UFO sightings before this and I would like to know what could have made this happen in the sky, I am just curious. I am one of several people that were very confused by this experience and can’t wait to hear what it really was.Thank You, J.
