A technical log from a flight from Bali to Jakarta on Sunday said an instrument was "unreliable" and the pilot had to hand over to the first officer.

The Boeing 737 airliner crashed into the sea with 189 people on board.

It went down after taking off from Jakarta. There is no sign of survivors.

The BBC has so far been unable to reach Lion Air, the low-cost airline which owns the plane, for comment.

Flight JT 610 was headed for the western city of Pangkal Pinang on Monday when it came down. Rescuers have recovered some bodies and personal items, including baby shoes. Families are being told to go to a hospital to identify the dead.

The incident is reported to be the first major accident involving a Boeing 737 Max - an updated version of the 737.

A technical log obtained by the BBC from the plane's previous flight suggests that the airspeed reading on the captain's instrument was unreliable, and the altitude readings differed on the captain's and first officer's instruments.

"Identified that CAPT [captain's] instrument was unreliable and handover control to FO [first officer]," the log reads. "Continue NNC of Airspeed Unreliable and ALT disagree."

The crew decided to continue their flight and landed safely at Jakarta.

Earlier Lion Air Chief Executive Edward Sirait said the plane had had an unspecified "technical issue" when flying from Denpasar in Bali to Jakarta, but he added that this had been "resolved".

"If the plane was broken, it would have been impossible to clear the plane to fly from Denpasar," he said. "When we received the flight crew's report, we immediately fixed the problem."

The airline operates 11 Boeing 737 Max 8 planes but the others have not had a similar technical problem and there is no plan to ground the fleet, he added.

Flight JT 610 took off from Jakarta at 06:20 on Monday (23:30 GMT on Sunday).

It was due to arrive at Depati Amir airport in Pangkal Pinang an hour later but 13 minutes into the flight, authorities lost contact.

The pilot had asked to return to Jakarta's Soekarno-Hatta airport, officials say.

The head of Indonesia's disaster agency, Sutopo Purwo Nugroho, has tweeted images of debris and personal belongings that came from the aircraft and had been found floating in the sea.

Lion Air said in a statement that the pilot and co-pilot had had more than 11,000 flight hours between them.

Three of the crew on board were trainee flight attendants and one was a technician.

Twenty employees from Indonesia's finance ministry were also on board, the BBC has learned.

A ministry spokesperson said they had worked at the finance ministry offices in Pangkal Pinang but had been in Jakarta for the weekend.

The 737 Max series are the fastest-selling planes in Boeing's history and there are four models - the Max 7, Max 8, Max 9 and Max 10.

The Boeing 737 Max 8 has been in commercial use since 2016.

The aircraft involved in the crash was made in 2018. It is a single-aisle plane used for short-haul travel.

In a statement, Boeing expressed sympathy for the victims and families and said it stood "ready to provide technical assistance to the accident investigation".

Australia told government workers and contractors to stop using the airline until the findings of the investigation were out.

Indonesia, a vast archipelago, is heavily reliant on air travel but many of its airlines have a poor safety record.

Established in 1999, Lion Air operates domestic flights as well as international routes to South East Asia, Australia and the Middle East.

It has had issues of safety and poor management in the past and was banned from flying into European airspace until 2016.

In 2013, Lion Air flight 904 crashed into the sea on landing at Bali's International Airport. All 108 people on board survived. In 2004, flight 538 from Jakarta crashed and broke up on landing at Solo City, killing 25 people.

In 2011 and 2012 a number of pilots were found in possession of methamphetamines, in one incident hours before a flight.

There will also be an online archive, showing all of your previous ads, roughly how much you spent, and who they have reached. The archive can be searched by anyone, whether or not they are a Facebook member.

The new system has already been in operation in the US and Brazil.

Facebook was forced to act following controversy about ads it displayed during the 2016 US Presidential election campaign and the UK's EU referendum.

In the United States, thousands of ads were bought by Russian groups trying to sow discord. Facebook has been under pressure to make sure the same thing did not happen in the run-up to November's mid-term elections.

Facebook insists that Russian spending on ads during the Brexit campaign amounted to just £0.73, although the Department of Culture, Media and Sport Select Committee was unhappy with the level of information provided by the company.

The first time anyone wants to place an advert that features political figures and parties, elections, legislation before Parliament and past referendums such as those involving Scottish independence or Brexit, they will go through a verification process to prove their identity and that they are based in the UK. They will have to provide a passport, a driving licence or a residence permit, and these will be checked by a third-party organisation.

Searching the archive, you come across examples of ads that have been placed without the "paid for by" label.

Facebook then shows this message: "After the ad started running, we determined that the ad was related to politics and issues of national importance and required the label. The ad was taken down."

The system allows users to report a political ad as fake news, and if Facebook determines that it does contain falsehoods, it can be taken down. Adverts that have broken the rules remain in the archive, so that you can check just how many people it reached while it was on the site.

In a blog about the new policy, Facebook says that in the US and Brazil it is pleased with the progress made so far. But the company admits that it will not cut out abuse entirely.

"We're up against smart and well-funded adversaries who change their tactics as we spot abuse," it says.

Last week, the social network removed more than 500 pages and 250 accounts it said were spamming users with what it called "sensational political content" to gain attention as the US mid-term elections approached.

Facebook suggested the motives behind the material were financial rather than political, designed to get users clicking on adverts.

The new rules will not necessarily show who has broken the UK's laws on election spending. The message that must be displayed on any ad will only show who paid Facebook for it, not where their money came from.

That, says Facebook, would be a matter for the Electoral Commission to investigate. In July, the commission found that the Brexit campaign group Vote Leave had broken the law by funnelling money for Facebook ads through a youth group, BeLeave.

Facebook says in future spending on adverts will be more visible.

"The goal is to make it transparent, so that people can see that - not after the fact, but while the campaigning is going on," says Rob Leathern, the executive in charge of the initiative.

In the US, the library has recorded over one million political ads since it launched in late May.

Spending in the UK will presumably be pretty low for the time being - unless there is a snap election. But when a vote comes, we can expect Facebook's ad archive to become an essential tool - not just for the electorate but for parties trying to work out what their opponents are up to.
