Q: (CNN) -- North Korea resumed firing near its sea border with South Korea on Thursday, South Korean media said, citing Seoul officials. Artillery shells were fired toward South Korean-controlled Yeonpyeong Island, Yonhap News Agency quoted the officials as saying, adding that the shells fell in waters north of the Northern Limit Line (NLL), the de facto inter-Korean maritime border. The North fired artillery shells on Wednesday in the same area, saying they were part of an annual training drill. "We have confirmed North Korea's firing of several artillery shells, but they did not cross" the two countries' maritime border, said Park Sung-woo, of Seoul's joint chiefs of staff, according to Yonhap. "We are on high military alert." "Following the firing by North Korea, South Korea responded by shooting vulcan canons into the air, a statement that it would not be intimidated by saber-rattling by the communist neighbor," Yonhap said. There were no reports of casualties. Also Thursday, a South Korean Unification Ministry spokesman said that despite the tension, talks slated for Monday with North Korea would still go forward in the North Korean border town of Kaesong, Yonhap reported. Seventeen South Korean officials are expected to attend those talks, Yonhap cited Chun Hae-sung, the official, as saying.

Q: (CNN) -- The flight data and cockpit voice recorders from JetBlue Flight 191, which made an emergency landing this week, have been retrieved and will be analyzed, officials said Thursday. The National Transportation Safety Board will download the data Friday, said spokeswoman Kelly Nantel. Information gleaned from them will be given to the FBI, she said. Investigators are looking into the apparent midair meltdown of the captain, Clayton Osbon, whose remarks and erratic behavior Tuesday led the co-pilot to lock him out of the cockpit. Crew and passengers subdued Osbon as he screamed and banged on the door so hard the first officer thought Osbon would come through, according to a federal criminal complaint filed Wednesday against Osbon. The complaint says Osbon began making remarks during the flight that concerned the first officer, who is his co-pilot. "Osbon yelled over the radio to air traffic control and instructed them to be quiet. Osbon turned off the radios in the aircraft, dimmed his monitors and sternly admonished the FO (first officer) for trying to talk on the radio," the U.S. attorney's office in the Northern District of Texas said in a written statement. "When Osbon said 'we need to take a leap of faith,' the FO stated that he became very worried. Osbon told the FO that 'we're not going to Vegas,' and began giving what the FO described as a sermon." It was not immediately known whether the alleged remarks are audible on the voice recorder. But federal regulations state that planes manufactured since 1991 must record cockpit chatter on microphones. The JetBlue plane was new and would be subject to the rule. The cockpit voice recorder captures two hours of data and the flight data recorder, which measures the plane's speed and altitude, contains 25 hours. About 3Â½ hours into the planned five-hour flight from New York's Kennedy International Airport to Las Vegas, the pilot left the cockpit to use the lavatory, but he failed to follow security protocol, alarming the crew, according to an affidavit filed in support of an arrest warrant. He then banged on the lavatory door and told the female passenger inside that he needed to go to the bathroom. By that time, the first officer had summoned another JetBlue pilot who had been traveling as a passenger to enter the cockpit and the two locked themselves inside, the affidavit states. From the cabin, Osbon tried to enter his security code to gain access to the cockpit "and he banged on the door hard enough that the FO thought he was coming through the door," according to the affidavit. But the door held and, over the PA, the first officer ordered passengers to restrain Osbon. Several did just that, subduing the pilot in the forward galley. Osbon, who was been charged with interfering with a flight crew, has not made a public statement. He has been suspended pending an investigation and is receiving medical treatment, the airline said Wednesday. A court official said Osbon was still under care Thursday. JetBlue has repeatedly praised the first officer, along with an off-duty captain who stepped in to assist and other crew members. Some passengers have referred to the first officer as a hero. But his mother said on Thursday that he would reject the label. "Knowing my son, he would think that he's not a hero. He just did what he was paid to do," Jean Beatrice Dowd said of Jason Dowd. "That's just his job, and he loves his job. He's just a quiet man." He called his parents the night of the incident, his mother said. "He was pretty shaken up, and he couldn't say much." The incident took place on a significant date for the family -- the 10th anniversary of the death of Jason Dowd's older sister, who died of cancer, Jean Dowd said. "I know he was thinking of her, too, at the time this was all going on," Dowd said. The incident "has been earthshaking for us, too," she said. "To lose him would have been terrible for us." Jason Dowd, 41, who is married and has two young children, has not made a public statement. He was in New York, speaking with officials about the incident, his mother said. After the incident, the flight made the emergency landing in Amarillo, Texas. Osbon's stepmother said Thursday she has flown with him several times. "He loved to fly, a love which he got from his dad," Judy Osbon said in a statement. "He also took his piloting very seriously and was very good at it. I've only known Clayton to be a cheerful, conscientious and caring person." Her stepson was upbeat the last time they spoke, she said. Osbon's father, Ronald, who was a pilot, and a passenger were killed in a 1995 airplane crash in Florida, according to the National Transportation Safety Board. The pilot radioed he was losing power on both engines and was out of gas. The aircraft crashed near Daytona Beach Regional Airport. CNN's Aaron Cooper, Mike M. Ahlers and Carol Cratty contributed to this report.

Q: Madrid (CNN) -- Spanish rail chiefs testified on safety before lawmakers Thursday, two weeks after 79 people died and scores were injured in a horrific derailment in northwestern Spain. The investigation has focused on the actions of the train's driver, Francisco Jose Garzon, but questions have also been asked about the safety systems in place on Spain's national railway network. Gonzalo Ferre Molto, president of state-owned rail infrastructure company Adif, and Julio Gomez-Pomar, president of state railroad company Renfe, outlined what is being done to ensure the safety of rail travelers. "My desire is to know the whole truth and avoid the possibility of an event of this nature happening again," said Ferre. "This is the best service we can offer to the victims and the whole Spanish society." Lawmakers heard that the route the train was on, from Madrid to Ferrol, includes a mix of conventional and high-speed track, with the latter allowing high-speed trains to travel at over 200 kilometers per hour (124 mph.) Driver on phone when train derailed, court says . Two different safety systems are used in Spain: the European Rail Traffic Management System for the high-speed track and another known as ASFA on conventional lines. The train and its engineer were switching between the two kinds of track and operating system in the course of the journey. A transition from an ERTMS-operated section to the other system happened about four miles before the train derailed on a curve near the northwestern city of Santiago de Compostela, Ferre said. That section of track had been inspected on April 20, he said. Speed limit on bend . Court officials have said the train was traveling at 153 kph (95 mph) when it derailed, nearly twice the speed limit on the curve where the accident happened. Victims mourned at memorial mass . After the accident, a temporary speed limit of 30 kph was imposed on the stretch where the accident occurred and is still in place, Ferre said. A permanent limit of 60 kph will come into force once that is lifted. "Our safety department is developing an investigation report," Ferre told the parliamentarians. "Safety in the rail sector is an open subject." Gomez-Pomar said Renfe has started to examine the safety systems in place and admitted that they can be improved. He said the driver had taken control of the train at Ourense station at 8:06 p.m., about 35 minutes before the crash occurred. Garzon had started his working day about eight hours earlier, but his effective driving time at that point was less than three hours, he said. The driver, who has worked for Renfe since 1992, had passed his most recent health test, Gomez-Pomar said. He had been qualified to travel the Ourense-Santiago stretch of track since February 2012 and was given permission to drive the kind of train involved in the crash last November. In total, more than 7,000 trains have passed through the stretch where the accident occurred, Gomez-Pomar said. Human error . Some lawmakers from smaller parliamentary groups criticized what they said was a rush to blame the driver for the crash. "Shifting the responsibility of a high-speed train on to the machine operator is, from our point of view, a rather excessive responsibility," said Rosana Perez, of the Mixed Group. She suggested the number of drivers aboard a train should be increased as a safety measure to protect against human error. "It has been said that the only cause is the human factor. If it is really so, we are lost. This argument falls by its own weight," said Gaspar Llamazares, of the United Left group. Charges filed . Investigations continue into the cause of the July 24 derailment, which shocked the nation. As of Thursday, 38 people remain in the hospital, six of them -- all adults -- in critical condition, according to local health authorities. No nationalities were given for those still hospitalized. Authorities have charged Garzon with 79 counts of homicide by professional recklessness and an undetermined number of counts of causing injury by professional recklessness. He has been given conditional release but has surrendered his passport. Three witnesses were expected to give statements Thursday to a court in Galicia, in a closed-door session. They are a station manager and two neighbors who went to help the survivors immediately after the crash. Minutes before the derailment, Garzon received a call on his work phone, apparently receiving instructions on the way to Ferrol from a Renfe staff member, a court in Galicia said last month. The train was nearing the end of the six-hour trip between the capital and Ferrol at the time of the accident. Spain train crash victim: 'It felt like a roller coaster' CNN's Laura Perez Maestro and Al Goodman reported from Madrid, and Laura Smith-Spark wrote in London.
