The Air Force was conducting training with the UAV Raven at about 4 p.m. Tuesday when the aircraft was launched from an open field in the 500 block of Southeast 25th Avenue in Ocala.

Upon launch, the Raven immediately turned eastward and failed to respond to all commands from the controllers, Ocala police said.

The Raven, which has an approximate wingspan of 6 feet, landed at an unknown location, possibly in the Ocala National Forest, police said.

Air Force officials who said they want to recover the Raven are seeking help in locating it.

The Raven can fly up to 6.2 miles at speeds up to 60 mph, according to officials.

Anyone with information on the location of the device is asked to contact the Ocala Police Department.
