Kim Jong-un invited the world’s media to yesterday's anniversary celebrations in Pyongyang, where several ballistic weapons were pointedly on display in a clear warning to the world not to interfere with the country's nuclear programme.
The North Korean leader smiled as he watched his weaponry roll through the streets, followed by tanks, rocket launchers and goose-stepping soldiers.
But some who watched the parade were drawn to at least one wonky-looking missile that passed behind BBC reporter John Sudworth as he delivered a piece to camera.
Viewers have speculated over whether some or all of the rockets were fake
#NorthKorea missiles obviously fake how would they move that many across a country without the world knowing

The flimsy looking rocket was ponting skyward and its nose cone looked slightly bent.
It led to many people speculating whether the whole munitions display was fake.
One Twitter user said: "Fake missiles; bodied over wooden frames."
Another said: "I can't speak 2 the skills of #NorthKorea weapon engineers, but looking at these fake missiles their papier-mache experts are off the chain."
The suggestion Kim was bluffing about his military power comes after a failed missile launch yesterday which US vice president Mike Pence called "a provocation".
South Korean officials claim the failed launch may have a new intercontinental ballistic missile (ICBM), which Kim Jong-un had pledged was close to its testing phase at the beginning of this year.
A South Korean official said: “It's presumed to be new ICBM… longer than existing KN-08 or KN-14 ICBMs.”

He said: "This morning's provocation from the North is just the latest reminder of the risks each one of you face every day in the defence of the freedom of the people of South Korea and the defence of America in this part of the world.
"In these troubled times in this part of the world your courage and your valour still amazes the American people."
The US Vice President was speaking after American officials said a North Korean medium-range missile exploded seconds after it was launched on Sunday.
