UFO over Los Angeles

"In June of 2007, I was at Universal Studios in Los Angeles, California. I was taking a picture of the city. When I developed the pics, I noticed a rocket-like shape to the lower right of the city."

So what is this bone-shaped object? It's doesn't look like an airliner, and it's unlikely to be a rocket, as Animal44111 described. Is it an insect? A bird? Dirt on the camera lens? Scrutinize this photo with your best UFO skills and tell us what you think it is.
