Boeing 737-800 engine cover falls off during Southwest flight

A Houston-bound Boeing 737-800 plane operated by Southwest Airlines returned safely to Denver International Airport on Sunday after an engine cover fell off and struck the wing flap, according to the Federal Aviation Administration.
The agency said it will investigate.
In recorded air traffic control audio, one of the pilots said that “several passengers and flight attendants heard something loud hit the wing.”
In a statement to CNN, Southwest said passengers would take another plane to Houston and would be approximately three hours behind schedule.
“We apologize for the inconvenience of their delay but place our highest priority on ultimate Safety for our Customers and Employees,” the statement said. Southwest said no injuries were reported.
