As Travel and Leisure reports, users discussed this over on question-and-answer forum Quora and were lucky enough to get an explanation from an engineer. Or at the very least, a user claiming to be an engineer; there is, of course, no way to verify these claims.

Nevertheless, user P.J. Harb walked the users through the experiment. For the sake of simplicity, imagine that every passenger on the plane weighs 165 pounds. Multiplied by 300 passengers that equates to 49,500 pounds. If they all jumped at once, they’d exert that weight onto the floor of the craft all at once.

Now, the plane itself, when loaded with passengers, fuel, and luggage, weighs about half a million pounds. Long story short, if all of the passengers jumped at once, the experiment would impart a fraction of the weight of the craft into the equation. The pilot may feel “some vibrations,” as Harb noted, but otherwise, the plane’s autopilot mechanism will automatically correct for any changes to the flight path, and that will be it. So, as Travel and Leisure writer Stacey Leasca notes, if an impromptu dance party breaks out on the plane, it’s still going to land perfectly safely.
