The search for a missing plane has been expanded. The new search area has been expanded to an 18-hundred square mile zone in Eastern Arizona.

The single-engine plane piloted by Cynthia Anderson took off Monday from Winslow heading to Henderson, Nevada. A search was launched when relatives reported her overdue.

Anderson is a nurse on the Navajo Reservation in northeastern Arizona. The Arizona Division of Emergency Management is coordinating the search.

Searchers asked for support from Arizona National Guard Black Hawk helicopters. Fixed-wing aircraft with the Civil Air Patrol have been searching an area northeast of Phoenix where Anderson’s Cirrus SR-22 was last tracked on Tuesday.

Anderson’s last known radar location was 37 miles north of Globe. Officials believe she was heading southeast toward the Chandler Airport to avoid bad weather.
