EAST FELICIANA - First responders say their Thursday night search for a plane that reportedly went down near River Road south of LA-10 was eventually determined to be a false alarm. 

This update was provided Friday morning, around 7 a.m., with officials reporting that neither was a plane nor any debris found in the area.  

On Thursday night, sources said members of law enforcement were dispatched after emergency operators received 911 calls from residents who reported seeing a plane clip power lines as it descended.

Authorities say they also received a report of seeing a red beacon locator glowing in a field. 

A helicopter was used to search the area, and law enforcement set up a staging location, but no indication of a crashed plane was found.

On its Facebook page, the East Feliciana Sheriff's Office provided a possible reason why the possible plane crash was reported, explaining, "Last evening a tree fell on a DEMCO powerline in the area of the reported crash. The tree caught fire. The shorted lines caused a transformer to make a noise like an explosion. The caller saw and heard an airplane in the area at the same time.

During this time the area was overflown by a National Guard Blackhawk helicopter, call sign MOJO 38, flying out of the Hammond Airport. Our best guess is that this cascade of events was unfortunately misinterpreted as an airplane crash. We fully believe that the caller truly believed that a crash had occurred.

On a positive note, no one was injured and the event served as a valuable training exercise."
