An American Airlines flight was forced to make an emergency landing at Dallas/Fort Worth International Airport on January 17, after a fan problem onboard sent an odor of smoke through the cockpit and passenger cabin.

In this video, flight attendants can be heard making an announcement about emergency landing procedures, including how to properly brace. Later, multiple flight staff can be heard shouting for passengers to “brace” and to “grab your ankles and keep your heads down” as the aircraft landed.

The uploader, Scottsdale native Steve Ramsthel, told a Phoenix news outlet that he was impressed by how calm all of the passengers had remained.
