We were driving north on Idaho St. at 12:35 pm. I looked up, where the flight path normally is for the planes flying into LAX. However, I saw a pink line in the skin, but upon taking a picture, it was boomerang shape. I continued to watch it at the red light and took three pictures. Two of the pictures have airplanes inside them. When the light turned green, I continued north on Idaho St. and pulled into the gas station on the corner of La Habra Blvd. I then took another picture that clearly was the boomerang shape. We then drove east on La Habra Blvd to head home. While driving north on Euclid Ave above La Habra Blvd. the object disappeared.
