What are spy balloons and why could they play a key role in the future of aerial reconnaissance?
In an era of orbital satellites so advanced that they are able to make out objects half the size of cars from space, a spy balloon might seem like a bit of a relic.
They were a prominent tool for reconnaissance during the Cold War and were even used in a more basic form for intelligence gathering in the Napoleonic Wars more than 200 years ago.
But security experts say the balloons are just the “tip of a revolution” in the development and use of new high-altitude surveillance craft, with the UK even investing millions in a project to develop spy balloons last year.
On Saturday, the US shot down a suspected Chinese spy balloon that had been flying over its airspace.
A senior defence official had previously said the US has “very high confidence” it was a Chinese high-altitude balloon and was flying over sensitive sites to collect information, while China has not immediately denied the balloon belonged to them.
The Pentagon acknowledged reports of a second balloon that was spotted flying over Latin America, saying: “We now assess it is another Chinese surveillance balloon”.

The sightings prompted US Secretary of State Antony Blinken to postpone a high-profile visit to China which had been due to begin on Sunday, while the Pentagon accused Beijing of spying on sensitive military sites.
Beijing admitted that the initial balloon had come from China, but insisted it was a “civilian airship” that had strayed into American airspace and that it was for meteorological and other scientific research.
What are spy balloons?
The devices are lightweight balloons, filled with gas, usually helium, and attached to a piece of spying equipment such as a long-range camera.
They can be launched from the ground and are sent up into the air where they can reach heights of between 60,000ft (18,000m) and 150,000ft (45,000m), above the flight paths of commercial aircraft in an area known as “near space”.
Once in the air, they travel using a mixture of air currents and pressurised air pockets, which can act as a form of steering.
Why are they still useful in the satellite era?
According to defence and security analyst Professor Michael Clarke, the biggest advantage of spy balloons over satellites are that they can study an area over a longer period of time.

“The advantage is they can stay in one place for a long time,” he told Sky News.
“Because of the way the Earth rotates, unless a satellite is over the Equator, you need three to five satellites going all the time to track the same spot.
“These balloons are also relatively cheap, and much easier to launch than a satellite.”
Will balloons continue to be used in future for spying?
Very much so, according to Professor Clarke.
Despite the wide use of satellite technology, countries including the UK are also focusing on the development and use of spycraft to operate in the upper atmosphere.
In August, it was announced the Ministry of Defence had agreed a £100m deal with US defence company Sierra Nevada to provide high-altitude unmanned balloons to be used for surveillance and reconnaissance.
Professor Clarke said: “(These balloons) are the very tip of the revolution for passive upper atmosphere aircraft.”
He said other defence firms, such as BAE, were working on ultralight solar-powered drones which are able to operate in the upper atmosphere and stay in place for up to 20 months.
Why have China used them now?
According to Professor Clarke, the use of these balloons, if indeed they were launched by China, will likely have been a message to the US following its decision to open new military bases in the Philippines.
“I think it’s a challenge,” he said.
“They (China) are signalling that if the US is going to come closer to them then they will be more aggressive with their surveillance.

“It is also caused a political issue in the US now, because it will be seen as a sign of weakness not to shoot it down.
“This causes some embarrassment, but the US doesn’t need to respond.”
The balloon was spotted over Billings, Montana, on Wednesday – close to one of the US’s three nuclear missile silo fields at Malmstrom Air Force Base.

Mao Ning, a Chinese foreign ministry spokesperson, says that those involved should be ‘cool-headed’
Military and defence leaders initially decided against shooting down the balloon due to the safety risk from falling debris.
Professor Clarke added: “I think the debris issue is a bit of an excuse. It was over one of the least densely populated areas of the US and if they needed to they could have asked everyone to stay inside.
“I don’t think they wanted to make it a bigger issue, because China are daring them to shoot it down and make it an international issue.”

Donald Trump says Vladimir Putin wants to meet – and that he and Barack Obama ‘probably’ like each other
Donald Trump says a meeting is being set up between himself and Vladimir Putin – and that he and Barack Obama “probably” like each other.
Republican US president-elect Mr Trump spoke to reporters at his Mar-a-Lago resort in Florida on Thursday, saying Russian president Mr Putin “wants to meet, and we are setting it up”.
“He has said that even publicly and we have to get that war over with. That’s a bloody mess,” Mr Trump said.
Kremlin spokesperson Dmitry Peskov said on Friday there was a “mutual desire” to set up a meeting – but added no details had been confirmed yet and that there may be progress once Mr Trump is inaugurated on 20 January.
“Moscow has repeatedly declared its openness to contacts with international leaders, including the US president, including Donald Trump,” Mr Peskov added.
“What is required is a mutual desire and political will to conduct dialogue and resolve existing problems through dialogue. We see that Mr Trump also declares his readiness to resolve problems through dialogue. We welcome this. There are still no specifics, we proceed from the mutual readiness for the meeting.”

Trump on Obama: ‘We just got along’
Mr Trump also made some lighter remarks regarding a viral exchange between himself and former Democrat President Barack Obama at Jimmy Carter’s funeral on Thursday.
The pair sat together for the late president’s service in Washington DC on Thursday, and could be seen speaking for several minutes as the remaining mourners filed in before it began.
Mr Obama was seen nodding as his successor spoke before breaking into a grin.
Asked about the exchange, Mr Trump said: “I didn’t realise how friendly it looked.
“I said, ‘boy, they look like two people that like each other’. And we probably do.
“We have a little different philosophies, right? But we probably do. I don’t know. We just got along. But I got along with just about everybody.”
The amicable exchange comes after years of criticising each other in the public eye; it was Mr Trump who spread the so-called “birther” conspiracy theory about Mr Obama in 2011, falsely asserting that he was not born in the United States.

Insults continued for years, with Mr Obama famously dedicating much of his final White House Correspondents’ Dinner speech in 2016 to jokes at his political rival’s expense.
Mr Trump has repeatedly attacked the Obamas, saying the former president was “ineffective” and “terrible” and calling former first lady Michelle Obama “nasty” as recently as October last year.
On Kamala Harris’s campaign trail last year, Mr Obama said Mr Trump was a “78-year-old billionaire who has not stopped whining about his problems since he rode down his golden escalator nine years ago”, while the former first lady said that “the consequences of him ever being president again are brutally serious.”
“He was asleep in his bed, where he still is right now, as I wait on the coroner.”

She said: “He just didn’t want to evacuate. He’s been living here since 1968, and he’s been in Altadena my whole life.
“Like all of us on this block, in four blocks, he didn’t think it was going to be this devastating.
“It jumped whole streets, and it hit this community, but it didn’t touch the mountainside at all.”
They’re still trying to process the apocalyptic scenes here and grieving for those who did not get out.
Kimiko said: “I have no words to explain my feelings at this point in time.
“I’m just silent and numb and just mentally trying to go through the process.”
Rodney Nickerson decided not to leave his Altadena home.

It would be impossible to exaggerate the scale of the destruction, cars burnt to a cinder, palm trees still alight, powerlines strewn across roads.
So many people have lost the roof over their head but there’s one thing Kimiko says she’ll never lose – her memories.
“Every laugh, every joke he told.
“He was a smart man. He read the LA Times from cover to cover and walked around the Rose Bowl every day.
“He was healthy, he was ambitious… but he went to sleep and died in his bed back there.”
The US Supreme Court has rejected a last-ditch attempt by Donald Trump to delay sentencing in the Stormy Daniels hush money case.
The president-elect was convicted on 34 counts last May in New York of falsifying business records relating to payments made to Ms Daniels before the 2016 presidential election.
Prosecutors claimed he had paid her $130,000 (£105,300) in hush money to not reveal details of what Ms Daniels said was a sexual relationship in 2006.
Mr Trump has denied any liaison with Ms Daniels or any wrongdoing.
By a majority, the Supreme Court found his sentencing would not be an insurmountable burden during the presidential transition since the presiding judge, Juan M Merchan, has indicated he will not give Mr Trump jail time, fines or probation.
Mr Trump’s attorneys argued that evidence used in the Manhattan trial violated last summer’s Supreme Court ruling giving Mr Trump broad immunity from prosecution over acts he took as president.
At the least, they said, the sentencing should be delayed while their appeals play out to avoid distracting Mr Trump during the presidential transition.

Mr Trump’s attorneys went to the justices after New York courts refused to postpone sentencing.
Judges in New York found that the convictions related to personal matters rather than Mr Trump’s official acts as president.
Mr Trump’s attorneys called the case politically motivated, and they said sentencing him now would be a “grave injustice” that threatens to disrupt the presidential transition as the Republican prepares to return to the White House.
Mr Trump has said he will appeal again: “I respect the court’s opinion – I think it was actually a very good opinion for us because you saw what they said, but they invited the appeal and the appeal is on the bigger issue. So, we’ll see how it works out,” he said at a dinner with Republican governors at his private club in Florida.
Because the New York case was a state, rather than federal crime, Mr Trump will not be able to pardon himself when he takes office on 20 January.
