Question: Orlando International Airport and Dubuque Regional Airport, are located in which country?
Context: Southwest Airlines Flight 3472 was a regularly scheduled passenger flight operating from New Orleans International Airport, LA to Orlando International Airport, FL.  On 27 August 2016, the Boeing 737-7H4 (WL), with 99 passengers and 5 crew, 12 minutes after departure from New Orleans, was climbing through 31,000 feet and heading east over the Gulf of Mexico when the aircraft's number one engine suffered an uncontained engine failure.  Debris from the engine punctured the left side of the fuselage causing a loss of cabin pressure and damaged the wing and empennage.  Oxygen masks were deployed to passengers while the crew initiated an emergency descent to 10,000 feet.  The aircraft then diverted to Pensacola International Airport for a safe landing on runway 17 about 20 minutes later without further incident.  While the aircraft sustained substantial damage, there were no injuries. B-52 Memorial Park is located within the Orlando International Airport just off the Beachline Expressway formerly the Bee Line near runway 18L.
