Oh, interesting. They even made a movie.

Once an engine breaks the question is whether or not it becomes unbalanced, that is one reason why they can become detached from the plane.
The account on that page seems to indicate that the engines didn't detach as a result of the bird strike. One detached upon impact with the river, and the other was still attached.
