UPDATE: A McMinn County family thinks they found the missing part to a Delta airplane, forced to make an emergency landing in Nashville this week. The family stumbled upon the parts when taking pictures in a field at their farm, Barham Jersey Farms. The FAA is investigating whether they belong to the Delta Boeing 717 originally headed from Atlanta to Chicago.

Neighbors near the Barham Jersey Farm went out earlier this week to test their new camera. When they stopped to get a snap shot of the cows -- they noticed a piece of debris; debris might solve the puzzle on what happened to Delta Flight 762. 

The Barham family dairy farm is usually pretty quiet but on Thursday FAA officials, the sheriff's department, and even inmates from the McMinn County Jail filled their fields. They were inspecting and looking for pieces that may belong to Delta Flight 762. “It's kinda crazy, never had this happen out here, it’s pretty cool,” said a family member of the farm, Tanner Barham.

Barham says his cousin and their neighbors were out testing their new camera when they stumbled upon the piece of debris.  He said he saw it a few days earlier and thought nothing of it. “I found a piece of metal in a cornfield, I thought it was a piece of the barn, I had no clue it was part of a plane.”

The family called the FAA Wednesday and on Thursday safety inspectors arrived to examine the pieces. Former NTSB chairman Jim Hall said he can't tell by looking at pictures if this is part of the Boeing 717.  But it's important for all the pieces to be collected and reviewed. “I've seen where even the smallest piece might lead you to understand what happened and make important changes to aviation safer.”

The pieces will go to a lab where inspectors will determine if this incident was human error or a mechanical issue. “This aircraft operates in other fleets and it’s important for aviation safety to try and determine what happened,” said Hall.

With more than 400 acres of land The Barham's said the search will not stop work on the farm. They continue to operate waiting for life to get back to normal. “It's pretty crazy, it happened out here. Nothing ever happens out here, pretty neat,” said Barham.

A Delta spokesman told Channel 3 the investigation continues and they are assisting the FAA with their investigation. The Barham family says 30 additional pieces were located on their farm today in a one mile span.

Channel 3 is still waiting on confirmation from the FAA if the pieces are part of the plane.
