The Burj Khalifa in Dubai is the tallest building in the world at 2,722ft high.
And these guys decided to jump off the top of it.
Vince Reffet and Fred Fugen, from France, jumped from a platform built especially for their unbelievable leap.
Both men clearly don't have a problem with heights.
The pair apparently trained for a year for their jump.
The footage is extraordinary.
“When I came the first time to Dubai and saw the tower I said: 'This is the dream, the highest building in the world,'” Reffe said.
“We don’t like to scare ourselves, that is not the goal,” Fugen added.
"People think you BASE jump because you are crazy, you like to get scared, but we like to fly, we like to have fun."
"If you scare yourself, there is no fun."
Both men were clearly delighted at completing the jump.
