An investigation has been launched after part of a Delta Airlines Boeing plane came off mid-flight and landed in a person’s driveway in North Carolina. A local in the city of Raleigh phoned 911 and complained that a metal sheet was in their driveway.

The FAA said it is working to determine if an aircraft part found in a Raleigh driveway belongs to a Delta 737.

ER, operated by Delta, lost part of its wing flap during flight from Atlanta to Raleigh-Durham, landing safely with 109 passengers.
