A Southwest Airlines jet bound from LaGuardia Airport blew an engine at 32,000 feet and got hit by shrapnel that smashed a window, setting off a desperate scramble by passengers to save a woman from getting sucked out. She later died, and seven others were injured.
Passengers dragged the woman back in as the sudden decompression of the cabin pulled her part way through the opening, but she was gravely injured.
The pilot of the plane, a twin-engine Boeing 737 bound from New York to Dallas with 149 people aboard, took it into a rapid descent and made an emergency landing in Philadelphia as passengers using oxygen masks that dropped from the ceiling said their prayers and braced for impact.
"I just remember holding my husband's hand, and we just prayed and prayed and prayed," said passenger Amanda Bourman, of New York. "And the thoughts that were going through my head of course were about my daughters, just wanting to see them again and give them a big hug so they wouldn't grow up without parents."
The dead woman was identified as Jennifer Riordan, a Wells Fargo bank executive and mother of two from Albuquerque, New Mexico. She was the first passenger killed in an accident involving a U.S. airline since 2009. The seven other victims suffered minor injuries.
The National Transportation Safety Board sent a team of investigators to Philadelphia.
NTSB chairman Robert Sumwalt said the engine will be taken apart and examined to understand what caused the failure. Photos of the plane on the tarmac showed a missing window and a chunk gone from the left engine, including part of its cover.
The NTSB said a preliminary examination of the blown jet engine of the Southwest Airlines plane showed evidence of "metal fatigue.''
In a late night news conference, Sumwalt said one of the engine's fan blades was separated and missing. Sumwalt said the blade was separated at the point where it would come into the hub and there was evidence of metal fatigue.
In a press conference Tuesday night, NTSB officials said a piece of the cowling — a metal cover for a vehicle or aircraft engine — was found about 60 miles northwest of where the plane landed.
The NTSB said they don't know when the engine was last inspected.
The NTSB said the pilot and co-pilot hit their checklist and conducted all their procedures, applauding them.
Passengers commended one of the pilots for her cool-headed handling of the emergency. She walked through the aisle and talked with passengers to make sure they were OK after the plane touched down.
"She has nerves of steel. That lady, I applaud her," said Alfred Tumlinson, of Corpus Christi, Texas. "I'm going to send her a Christmas card, I'm going to tell you that, with a gift certificate for getting me on the ground. She was awesome."
Tracking data from FlightAware.com showed Flight 1380 was heading west over Pennsylvania at about 32,200 feet (10 km) and traveling 500 mph (800 kph) when it abruptly turned toward Philadelphia.
Bourman said she was asleep near the back when she heard a loud noise and oxygen masks dropped.
"Everybody was crying and upset," she said. "You had a few passengers that were very strong, and they kept yelling to people, you know, 'It's OK! We're going to do this!'"
In a recording of conversations between the cockpit and air traffic controllers, an unidentified crew member reported that there was a hole in the plane and "someone went out."
Tumlinson said a man in a cowboy hat rushed forward a few rows "to grab that lady to pull her back in. She was out of the plane. He couldn't do it by himself, so another gentleman came over and helped to get her back in the plane, and they got her."
Another passenger, Eric Zilbert, an administrator with the California Education Department, said: "From her waist above, she was outside of the plane."
Passengers struggled to somehow plug the hole while giving the badly injured woman CPR.
Passengers did "some pretty amazing things under some pretty difficult circumstances," Philadelphia Fire Commissioner Adam Thiel said.
As the plane came in for a landing, everyone started yelling to brace for impact, then clapped after the aircraft touched down safely, Bourman said.
"We were very lucky to have such a skilled pilot and crew to see us through it," Zilbert said. "The plane was steady as a rock after it happened. I didn't have any fearing that it was out of control."
The last time a passenger died in an accident on a U.S. airliner was 2009 when 49 people on board and one on the ground were killed when a Continental Express plane crashed on a house near Buffalo, New York.
Southwest has about 700 planes, all of them 737s, including more than 500 737-700s like the one in Tuesday's accident. It is the world's largest operator of the 737. The 737 is the best-selling jetliner in the world and has a good safety record.
Southwest CEO Gary Kelly said in Dallas that there were no problems with the plane or its engine when it was inspected Sunday.
The jet's CFM56-7B engines were made by CFM International, jointly owned by General Electric and Safran Aircraft Engines of France. CFM said in a statement that the CFM56-7B has had "an outstanding safety and reliability record" since its debut in 1997, powering more than 6,700 aircraft worldwide.
Last year, the engine maker and the Federal Aviation Administration instructed airlines to make ultrasonic inspections of the fan blades of engines like those on the Southwest jet. The FAA said the move was prompted by a report of a fan blade failing and hurling debris. But it was unclear whether the particular engine that failed on Tuesday was covered by the directives.
"There's a ring around the engine that's meant to contain the engine pieces when this happens," said John Goglia, a former NTSB member. "In this case it didn't. That's going to be a big focal point for the NTSB — why didn't (the ring) do its job?"
In 2016, a Southwest Boeing 737-700 blew an engine as it flew from New Orleans to Orlando, Florida, and shrapnel tore a 5-by-16-inch hole just above the wing. The plane landed safely. The NTSB said a fan blade had broken off, apparently because of metal fatigue.
In a press conference Tuesday night, NTSB officials said a piece of the cowling — a metal cover for a vehicle or aircraft engine — was found 60 miles northwest of where the plane landed.
The NTSB said they don't know when the engine was last inspected.
A separate plane, which took off from LaGuardia less than 15 minutes after the Southwest plane, was also forced to make an emergency landing.
The Delta connection flight to Richmond, Virginia was diverted to Dulles International Airport just outside of downtown Washington, due to a reported problem with one of the aircraft's wheels, officials said.
Flight 5507, operated by Express Jet, landed safely around 12:25 p.m. and no injuries were reported.
Passengers and crew were loaded onto a bus and taken to Richmond.
The Federal Aviation Administration will investigate the emergency landing.
