Real Or Fake? How Emirates Filmed Their Viral Ad On Top Of Burj Khalifa

"Real or fake? A lot of you have asked this question and were here to answer it," wrote Emirates Airline.

UAE-based airlines Emirates recently released an ad filmed on top of the world's tallest building, and it instantly created a huge buzz on social media. The 30-second ad features Nicole Smith-Ludvik, a professional skydiving instructor, as an Emirates cabin crew member who stands atop the Burj Khalifa. In her hand, she holds a series of placards that read: "Moving the UAE to the UK Amber list has made us feel on top of the world. Fly Emirates. Fly better." While viewers initially do not get to see where Ms Smith-Ludvik is standing, the camera soon zooms out to reveal that she is actually on top of the Burj Khalifa.  Real or fake?

While the video created a buzz on social media with its innovative concept, a section of the Internet also raised doubts about its authenticity. Some on Twitter accused Emirates of using green screens to film the video instead of actually climbing to the top of the Burj Khalifa.
