NTSB says Southwest Airlines Flight 1380 landed at higher than usual speed for commercial jets

The National Transportation Safety Board (NTSB) held a press briefing Wednesday. NTSB chairman Robert Sumwalt addressed the media and answered questions that revealed more details about the deadly flight.

Federal investigators are looking into a jet engine failure during Southwest Airlines Flight 1380 from New York to Dallas. One passenger was killed and others were injured.

Wednesday evening, the coroner confirmed that Jennifer Riordan was killed after the engine blew and hurled shrapnel at the plane and died of blunt impact trauma of head, neck and torso. She apparently was wearing a seat belt, but was partially sucked out of the plane.

Sumwalt said the Southwest jet landed at an unusually high speed and that the woman who died onboard was in row 14.

NTSB is currently in the process of interviewing the pilots from Flight 1380 and a transcript of the cockpit voice recorder will be provided in the coming days.

Read updates below as they happened from Wednesday's press briefing (all times Eastern).

Concern over the jet fleet, engine

5:03 p.m.: Sumwalt said if there's concern over the jet fleet or engine, the NTSB will issue a warning as soon as possible. He stressed it's still to early to make that judgment.

Fan blade separated in 2 places

5 p.m.: There was a fatigue fracture where the #13 fan blade would have gone into the engine. That was the initiating event that caused a secondary failure of the jet engine.

Passenger who died was seated in row 14. NTSB structure group is working to determine how the window came out. They have found no window materials (acrylic) inside the airplane. They have removed the side wall to take a look at the fuselage denting from the inside.

NTSB is interviewing Southwest pilots

4:57 p.m.: NTSB is in the process of interviewing the pilots of Southwest Airlines Flight 1380.

Somalt said airline pilots are trained in engine failure, rapid decompression and emergency landings.

"The pilots seemed very calm and assured of what they were doing," Sumwalt said. "My hat is off to them ... they behaved in a matter their training would prepare them for."

"We got a long way to go"

4:53 p.m.: Sumwalt said that this press briefing will be the last one at the scene.

He said that "we got a long way to go" and that updates on the investigation will be publicized on the NTSB website and social media accounts.

NTSB tweets image of engine piece found by public

4:50 p.m.: NTSB tweeted the following image showing a piece of the engine cowling from Southwest Airlines Flight 1380.

NTSB urges the public to continue reporting if they come across any other engine pieces.

Cockpit voice recorder transcript will become public

4:48 p.m.: Somwalt said that a transcript of the cockpit voice recorder will be provided publicly when it's ready. He said that it will take days to compile the transcript as the audio during the landing will come from at least two different sources.

Residents are finding pieces of Southwest airplane

4:46 p.m.: Sumwalt said residents in Philadelphia are finding engine pieces. They are notifying NTSB and local law authorities they have found the components.

NTSB said they will tweet an image of a piece of engine that someone has reported finding.

NTSB says 144 passengers are providing videos and still photos from the incident.

Southwest plane landed at 190 mph

4:44 p.m.: Sumwalt said the Southwest plane landed at an airspeed of 165 knots (or 190 mph). The typical landing speed is usually 135 knots.

The flight crew elected to land with flaps 5 instead of flaps 30 or flaps 40 due to concern of aircraft control issues. This lead to a higher landing speed.

The time from the initial incident to touchdown was 22 minutes.

NTSB chairman takes the podium

4:42 p.m.: NTSB chairman Robert Sumwalt said the plane's vibration increased after the engine blew. He said the aircraft did an uncommanded left bank roll at 41 degrees. Commercial aircraft typically never surpass 20-25 degrees.

1 passenger killed; Southwest pilot praised

One passenger was killed and seven others were hurt after the twin-engine 737 blew an engine on the New York to Dallas flight. Jennifer Riordan, a married mother of two, died after engine parts shattered one of the plane's windows. There were 149 people aboard. Passengers are calling pilot Tammie Jo Shults a hero for calmly guiding the plane to safety.

Terrified passengers like Marty Martinez reached for oxygen masks as the plane rapidly descended. Martinez said that there was Wi-Fi on the plane so he was able to stream a Facebook video as the plane headed to Philadelphia International Airport for an emergency landing.

"I thought I was cataloging the last moments of my existence," Martinez told CBS News.

Investigators probe deadly Southwest Airlines flight

Federal investigators are looking into the deadly incident that took place at about 30,000 feet Tuesday when Southwest Airlines Flight 1380 experienced a jet engine failure.

The National Transportation Safety Board has said a preliminary examination of the blown jet engine showed evidence of "metal fatigue."
