The event did not take place in LA, CA, but hard to know when we are in an airplane.
My daughter in window seat saw it first, let me know and I saw a smoke trail with a red light then the light went out.
She first took some pictures, see above, and then took video. When the object turns there are no wings and my husband said it's probably a missile?
We were going 500 mph at 6 to 6.5 miles up in the air. I couldn't get video turned. MUFON case 71817.
Here is the video.
