JAKARTA, Indonesia (AP) — The search for the crashed Lion Air plane has found aircraft debris and passenger belongings on the seafloor but the object thought to be the fuselage is still eluding it, an Indonesian official said today, as chilling video of passengers boarding the fatal flight emerged.

Search and Rescue Agency chief Muhammad Syaugi said the seafloor findings give the search team confidence they will find the body of the aircraft. The location of the airplane’s “black box” flight data recorder has been identified, he said, but strong currents prevented it from being recovered.

“We saw belongings such as life jackets, pants, clothes scattered on the seabed,” Syaugi said. “We believe the fuselage will be around there, we hope that our target can be found.”

The 2-month-old Boeing 737 MAX 8 jet plunged into the Java Sea early Monday just minutes after taking off from Jakarta, killing all 189 people on board.

The disaster has reignited concerns about safety in Indonesia’s fast-growing aviation industry, which was recently removed from European Union and U.S. blacklists, and also raised doubts about the safety of Boeing’s new generation 737 MAX 8 plane.

Syaugi said one of the ships with high-tech equipment being used in the search dispatched a remote-operated vehicle that recorded parts of the aircraft on the seafloor but not the 72-foot-long object detected at a depth of 105 feet that is believed to be the fuselage. He said the area is about 1,300 feet from the coordinates where the airplane lost contact.

Three other objects in separate locations were reached by divers but turned out to be two sunken boats and a fish trap. A remote-operated vehicle was sent to the black box location “but the currents on the seabed were very strong, the ROV was carried away,” Syaugi said.

Searchers have sent 57 body bags containing human remains to police identification experts who on Wednesday said they’d identified their first victim, a 24-year-old woman, from a ring and a right hand.

Anguished family members have been providing samples for DNA tests and police say results are expected within 4-8 days.

Musyafak, the head of Said Sukanto Police Hospital, said nearly 150 samples for DNA testing have been collected but more are still needed, especially from parents and children of victims.

Boeing Co. experts were expected to arrive in Indonesia on Wednesday and Lion Air has said an “intense” internal investigation is underway in addition to the probe by safety regulators.

Data from flight-tracking sites show the plane had erratic speed and altitude in the early minutes of a flight on Sunday and on its fatal flight Monday. Safety experts caution, however, that the data must be checked for accuracy against the plane’s black boxes.

Several passengers on the Sunday flight from Bali to Jakarta have recounted problems that included a long-delayed takeoff for an engine check and terrifying descents in the first 10 minutes in the air.

Two interviewed on Indonesian TV recalled details such as a strange engine sound, a smell of burnt cables, and panicked passengers crying out for God to save them as the plane rapidly lost altitude. Later in the flight, a man who was either the captain or first officer walked through the plane and returned to the cockpit with what looked like a large manual.

Lion Air has said maintenance was carried out on the aircraft after the Sunday flight and a problem, which it didn’t specify, was fixed.

Indonesian TV broadcast a smartphone video of passengers boarding Flight 610, its mundane details transformed into unsettling moments by knowledge of the tragedy that would transpire.

It showed passengers’ boarding passes being checked and people walking along a concourse and then down stairs with bright red and white Lion Air jets visible on the tarmac.

At one point, the passenger who shot the video, Paul Ferdinand Ayorbaba, zoomed in on the flight number on his boarding pass. A part of the video shows passengers walking up the boarding stairs to a Lion jet.

“My husband sent that video to me via WhatsApp. It was his last contact with me, his last message to me,” said Inchy Ayorbaba, interviewed at the Jakarta police hospital where she had taken their three children for DNA tests.

The messaging app’s timestamp showed the video was sent about 35 minutes before the plane took off, said Ayorbaba, who first saw the message at 6:30 a.m., some 10 minutes after the plane departed, and then went back to sleep.

Lion Air’s technical director was removed from duty Wednesday at the order of the Transport Ministry. It also has ordered all Boeing 737 MAX 8 planes operated by Lion Air and national carrier Garuda to be inspected. Lion has ordered 50 of the jets, worth an estimated $6.2 billion, and currently operates nine.

Daniel Putut, a Lion Air managing director, said Tuesday evening the airline has many questions for Boeing.

“Of course there are lots of things we will ask them, we all have question marks here, ‘Why? What’s the matter with this new plane,’” Putut said.

The crash is the worst airline disaster in Indonesia since 1997, when 234 people died in the crash of a Garuda flight near Medan. In December 2014, an AirAsia flight from Surabaya to Singapore plunged into the sea, killing all 162 on board.

Indonesian airlines were barred in 2007 from flying to Europe because of safety concerns, though several were allowed to resume services in the following decade. The ban was completely lifted in June. The U.S. lifted a decadelong ban in 2016.

Lion Air, a discount carrier, is one of Indonesia’s youngest and biggest airlines, flying to dozens of domestic and international destinations. It has been expanding aggressively in Southeast Asia, a fast-growing region of more than 600 million people.

WASHINGTON (AP) — The Pentagon is deploying 5,200 troops to America’s southwest border in an extraordinary military operation a week before nationwide elections in which President Donald Trump wants voters to focus on a slow-moving “invasion” of Central American migrants.

The number of troops being sent is more than double the 2,000 who are in Syria fighting the Islamic State group.

Two caravans of would-be migrants, mostly on foot and seeking asylum, are still around a thousand miles from the U.S. border with Mexico.

Trump, eager to keep voters focused on illegal immigration in the lead-up to the elections, stepped up his dire warnings about the caravans, tweeting, “This is an invasion of our Country and our Military is waiting for you!”

Any migrants who complete the long trek to the border already face major hurdles — both physical and bureaucratic — to being allowed to stay in the United States.

In an interview late Monday, Trump said the U.S. would build “tent cities” for asylum seekers.

“We’re going to put tents up all over the place,” he told Fox News Channel’s Laura Ingraham. “They’re going to be very nice and they’re going to wait and if they don’t get asylum, they get out.”

Under current protocol, migrants who clear an initial screening are often released until their cases are decided in immigration court, which can take several years.

Trump denied his focus on the caravan is intended to help Republicans in next week’s midterms, saying, “This has nothing to do with elections.”

The Pentagon’s “Operation Faithful Patriot” was described by the commander of U.S. Northern Command as an effort to help Customs and Border Protection “harden the southern border” by stiffening defenses at and near legal entry points. Advanced helicopters will allow border protection agents to swoop down on migrants trying to cross illegally, said Air Force Gen. Terrence O’Shaughnessy.

Troops planned to bring heavy concertina wiring to unspool across open spaces between ports.

“We will not allow a large group to enter the U.S. in an unlawful and unsafe manner,” said Kevin McAleenan, commissioner of Customs and Border Protection.

Eight hundred troops already are on their way to southern Texas, O’Shaughnessy said, and their numbers will top 5,200 by week’s end. Some of the troops will be armed. He said troops would focus first on Texas, followed by Arizona and then California.

The troops will join the more than 2,000 National Guardsmen that Trump has already deployed to the border. It remained unclear Monday why the administration was choosing to send active-duty troops given that they will be limited to performing the same support functions the Guard already is doing.

The number of people in the first migrant caravan headed toward the U.S. has dwindled to about 4,000 from about 7,000 last week, though a second one was gaining steam and marked by violence. About 600 migrants in the second group tried to cross a bridge from Guatemala to Mexico en masse Monday. The riverbank standoff with Mexico police followed a more violent confrontation Sunday when the migrants used sticks and rocks against officers. One migrant was killed Sunday night by a head wound, but the cause was unclear.

The first group passed through the spot via the river — wading or on rafts — and was advancing through southern Mexico. That group appeared to begin as a collection of about 160 who decided to band together in Honduras for protection against the gangs who prey on migrants traveling alone and snowballed as the group moved north. They are mostly from Honduras, where it started, as well as El Salvador and Guatemala.

Another, smaller caravan earlier this year dwindled greatly as it passed through Mexico, with only about 200 making it to the California border.

Migrants are entitled under both U.S. and international law to apply for asylum. But there already is a bottleneck of would-be asylum seekers waiting at some U.S. border crossings to make their claims, some waiting as long as five weeks.

McAleenan said the aim of the operation was to deter migrants from crossing illegally, but he conceded his officers were overwhelmed by a surge of asylum seekers at border crossings. He also said Mexico was prepared to offer asylum to members of the caravan.

“If you’re already seeking asylum, you’ve been given a generous offer,” he said of Mexico. “We want to work with Mexico to manage that flow.”

The White House is also weighing additional border security measures, including blocking those traveling in the caravan from seeking legal asylum and preventing them from entering the U.S.

The military operation drew quick criticism.

“Sending active military forces to our southern border is not only a huge waste of taxpayer money, but an unnecessary course of action that will further terrorize and militarize our border communities,” said Shaw Drake of the American Civil Liberties Union’s border rights center at El Paso, Texas.

Military personnel are legally prohibited from engaging in immigration enforcement. The troops will include military police, combat engineers and others helping on the border.

The escalating rhetoric over the migrants and expected deployments come as the president has been trying to turn the caravans into a key election issue just days before elections that will determine whether Republicans maintain control of Congress.

“This will be the election of the caravans, the Kavanaughs, law and order, tax cuts, and you know what else? It’s going to be the election of common sense,” Trump said at a rally in Illinois on Saturday night.

On Monday, he tweeted without providing evidence, “Many Gang Members and some very bad people are mixed into the Caravan heading to our Southern Border.”

“Please go back,” he urged them, “you will not be admitted into the United States unless you go through the legal process. This is an invasion of our Country and our Military is waiting for you!”

It’s possible there are criminals mixed in, but Trump has not substantiated his claim that members of the MS-13 gang, in particular, are among them.

The troops are expected to perform a wide variety of functions such as transporting supplies for the Border Patrol, but not engage directly with migrants seeking to cross the border, officials said. One U.S. official said the troops will be sent initially to staging bases in California, Texas and Arizona while the CBP works out precisely where it wants the troops positioned. U.S. Transportation Command posted a video on its Facebook page Monday of a C-17 transport plane that it said was delivering Army equipment to the Southwest border in support of the operation.

The U.S. military has already begun delivering jersey barriers to the southern border in conjunction with the deployment plans.
