It's about 17min long, entertaining...his description:
"Let's say you're traveling at about 17,500 miles per hour (28,000 km/h) in low earth orbit, your main engines are out of fuel, and it's your job to guide the spaceship through a fiery re-entry without burning up or skipping out of the atmosphere, navigate to your landing site, and arrive with just enough energy to make an unpowered landing on a runway which is halfway around the planet from where you started. And, of course, either you succeed on your first try, or everyone dies. So, no pressure…. In this talk, I'll show you how space shuttle designers, pilots, and autopilots managed to do just that."
