After spending hours on a hot Las Vegas tarmac with no A/C, food, or water (which may not be entirely legal), passengers aboard a Phoenix-bound Allegiant Air flight decided to kick start the plane by breaking out in a spirited rendition of R. Kelly's "I Believe I Can Fly."

Or maybe, as the video's description suggests, the passengers were simply "delirious from heat" and "banded together in song" in order "to avoid a mutiny" after "two people passed out" and "two vomited."

Either way, good times.
