Casade Mountains, Cultus lake, UFO

On march 25-th 2011 my husband and I witnessed couple bright objects on the sky. It was 9.20 PM. One of them was hovering about 10 minutes. Location: over Cascade Mountains, Cultus Lake, slightly East-North from it, Promontory direction. It was looking like a star but very bright and blinking white, red and blue. It disappeared ones, but just to change its position on high latitude (I guess) it became a bit smaller. The second one appears for few seconds close to the main one, position 5 o’clock. No other stars were visible at the time. I made 3 videos, not very good quality but still. Here is one of them:

I found two other videos somehow related to my sighing:
