As his plane made a rapid descent to normalize cabin pressure, a Southwest Airlines pilot went on the plane’s loudspeaker and apparently told passengers the aircraft was going down. “At first it sounded like someone was coming over the PA to talk. Then it sounded like shots through the cabin, twice, back to back,” passenger Grace Stroud told CNN. “Seconds later, the panicked captain said, ‘We’re in trouble; we’re going down.'” Another passenger, Shelley Wills, told CNN affiliate WTVD that the pilot made the remarks as the plane went into a nosedive when it neared the Raleigh-Durham International Airport. “He said, ‘We’re going down.’ And everyone is looking around like, ‘Is this a joke? Is he serious?’ And then you felt the nosedive.” Soon after, the Boeing 737 leveled out and made an emergency landing at the Raleigh airport.
