During a recent flight from Colorado Springs to San Diego, a group of college students got up from their seats and began dancing to the internet craze, Harlem Shake resulting in an investigation by the Federal Aviation Administration.

Matt Zelin, a sophomore, told the Colorado College newspaper, The Catalyst, he asked a flight attendant for permission beforehand.

FAA spokesman Allen Kenitzer said Thursday they're looking at what phase the flight was in during the dance in the aisles.

Frontier Airlines says the seatbelt sign was off and safety measures were followed.

The Harlem Shake which has become a popular YouTube video, shows one person starting to dance, and then the video cuts to a large group of people dancing, many in costume.
