Kim Jong-un's Ilyushin jet takes off from China.
Kim Jong-un's Soviet-era Ilyushin-62M plane set to fly him from North Korea to Singapore
Kim Jong-un's trip to Singapore marks a rare occasion the North Korean leader is heading overseas.
Following a family tradition, Mr Kim is known to use a special armoured train for travel.
But of course that's not an option for getting to the island-state of Singapore.
So just how will Mr Kim make the big trip? A plane of course!
Kim Jong-un arrives in Dalian, China last month
Mr Kim made his first international trip by air since becoming leader in 2011 when he visited China last month for a meeting with Xi Jinping.
He flew on his personal Ilyushin-62M jet, named Chammae-1 after the country's national bird, the Goshawk.
An Ilyushin cargo plane was also part of trip.
It seems this will also be his transport of choice to get to Singapore.
What is an Ilyushin-62M?

It's a Soviet-era airliner first conceived in Russia in the 1960s, with the last ones produced in the mid-1990s.
It was said to be the world's biggest jet airliner when it was first flown in 1963.
It's just over 50 metres long and as a passenger plane could carry nearly 200 passengers.
But there are now very few left in service around the world.
Can such an old plane make it to Singapore?

There is speculation Singapore was more favoured for the summit over, say, Geneva because of fears the North Korean
delegation would have trouble getting themselves that far.
The Ilyushin-62M has a range of about 10,000 kilometres, which puts Singapore safely within non-stop flying distance.
But there have been questions about the mechanical reliability and absence of advanced communications systems
typical of modern planes.
And Mr Kim's cargo plane, carrying things like his limousine, can't fly as far with a full load and might need to stop for
refuelling along the way.
