Hollywood filmmakers have long obeyed the rule: “Viewers will believe anything if they see it.” And so we’ve been treated to marauding dinosaurs, exploding planets, and high speed chases the wrong way on superhighways. Yet when YouTube superstar Casey Neistat posted a video titled “ Human Flying Drone,” some among the 9.5 million viewers suspected that the stunt—shot in Finland and sponsored by Samsung— had been faked. These skeptics didn’t believe Neistat would have trusted a 16-motor drone to hoist him high above snow-covered buildings in imitation of Santa Claus. What do you think?

One critic wrote a blog explaining why the flight was probably impossible. The blogger even speculated on how Neistat and his team created the appearance that he was flying. Many commenters added more reasons “proving” that the video was a sham.

The doubters put Neistat’s immense reputation—his vlogs have been viewed more than 2 billion times— —on the line. Neistat defended himself in the way he knows best: he vlogged a response. Like many “making of” featurettes, this one—shown below—is as fascinating as the movie it explains.  Neistat’s behind-the-scenes facts are persuasive. But equally powerful is his delivery. Neistat wasn’t defensive. He didn’t insult his critics. He didn’t pontificate. Like a good teacher, he simply spoke the truth. Many bloggers—and politicians for that matter—could learn a lot by studying Neistat’s follow-up video.
