People thought it had to be fake.

Dubai-based airline Emirates has released an advert featuring a woman standing on the top of the Burj Khalifa that is so unbelievable, people online assumed it was fake.  
But it’s all real.
The social media video ad was released to promote the United Arab Emirates (UAE) moving from the UK’s travel red list to amber. It begins with a close up of a woman dressed in full Emirates uniform, telling a story through written cards in Love Actually style.
As the final cards reading “Fly Emirates, Fly Better” are shown, the camera begins a rapid move backwards to reveal the woman standing atop the world’s tallest building, 830m above the ground.
Online commenters praised the ad for its use of computer graphics, but the airline revealed that none were used – the terrifying stunt was entirely real.
