A small airplane crashed in a wooded area of northwest Alabama, killing the pilot, authorities said.

News outlets reported that an aircraft traveling from Dallas to Knoxville, Tennessee, didn’t show up on time, prompting officials to use a signal to locate the cellphone of the pilot, who was the only person aboard.

A more than two-hour search that began late Wednesday ended when a state helicopter located wreckage near a wildlife management area in extreme northwest Alabama.

The Lauderdale County Sheriff’s Office identified the pilot as a 69-year-old man, but his name wasn’t released immediately.
