ARIZONA PLANE CRASH IN SUPERSTITION MOUNTAINS KILLS 2 PEOPLE: NTSB
The NTSB said in a tweet that it is investigating the crash of a Mooney M20R aircraft near Watertown, a city in Dodge and Jefferson counties about 48 miles northwest of Milwaukee.
Television helicopter footage from the scene showed apparent aircraft debris spread across a field and in an adjacent wooded area.
Mary Bellows, who lives in Watertown, told the Milwaukee Journal Sentinel that around noon she heard the plane and then a big boom. She said her room shook, and then a large plume of smoke rose near her home.
Local officials had not released any information about the crash by early afternoon. A message seeking comment and details on the crash was left by The Associated Press with the Watertown Police Department.
