The Coast Guard suspended its search Monday for a missing Long Island pilot and his plane.

Family members say 76-year-old Kennworth Eaton disappeared Saturday while flying his single-engine plane. His daughter says Eaton was supposed to take his Piper Cherokee for a quick test flight from Spadaro Airport in East Moriches to Gabreski Airport in Westhampton Beach.

Eaton?s family says he had over 30 years of flying experience. Eaton rented a trailer in East Moriches to be closer to his plane. He has six children and four grandchildren.

The Coast Guard says the search for Eaton included 30 square miles of Long Island on both land and water.
