Tim Morgan, a commercial pilot with years of experience, has created a ten minute video he claims will help anyone safely land a 737 in an emergency. The notion that someone could plop down in a cockpit, with zero experience, and pilot a 737 to a safe landing is ludicrous, but that doesn't make this video any less fascinating.
Morgan created the video to accompany his lengthy Quora response to the question: "What should I do if the pilot passes out and I (with no flight training) have to land the plane?" The article provides a wealth of information about piloting a jet and if you've ever been genuinely curious about what the countless knobs, dials, buttons and gauges in a cockpit do, it's certainly worth a read.
But should you find yourself on a flight where both pilots have lost consciousness, it's doubtful you'll be reaching for your phone in order to save the day. You'd need to be in an actual Boeing 737 cockpit for the instructions to make any sense, and the odds of downloading a ten minute video on crappy airline Wi-Fi before the inevitable happens are slim to none.
