United Airlines flight 1463 landed at Mid-Continent Airport just after 10:30 p.m. The John Wayne-bound flight left Chicago at 8:36 p.m.
A spokesman with the Federal Aviation Administration says an emergency evacuation slide inadvertently deployed in mid-flight. Initial reports that a passenger opened a door during the flight were false.
The FAA spokesman said, "it is impossible to open a door at that altitude."
According to Flight Aware, the plane was flying at 38,000 feet at 10:05 p.m. In 12 minutes, the plane dropped to 11,000 feet due to a loss in cabin pressure.
United Airlines released a statement saying 96 passengers and five crew members were on board the Boeing 737-700. All passengers were seated at the time the slide deployed. No one was hurt.
Some passengers say they heard a hiss and a pop, then saw the slide starting to expand.
"All the sudden you heard a bang and a hiss, and the crew had a panicked look and the ran toward the front of the plane. The whole
back part of the plane where they sat was full with the shoot," said Diane Mondini, passenger. "First thing that went through my mind was it probably popped out the door and we would lose pressure immediately, luckily, that did not happen it just inflated inside."
Passengers were taken off the plane about an hour after landing.
