Authorities have yet to release the names of two people who were killed in a small plane crash in central Iowa over the weekend. The crash happened Saturday afternoon in a remote area along the Des Moines River near Madrid.

The pilot and a passenger were killed. A fisherman reported seeing the crash and said the plane struck some power lines and nosedived into a sandbar in the river.

The plane — a restored, vintage World War II aircraft known as a Fairchild M-62 — was flying along the river from Boone to Ankeny when it crashed.
