Awesome Runways

San Francisco Internation Aiport’s runways 28L and 28R run in parallel, just 750 feet apart. As a result, jumbo jets often land next to each other. NickFlightX captured footage of a number of flights landing in this formation. They’re not always in sync, but some of them come in perfectly side-by-side.

Previously, CGP Grey explained the surprisingly simple numbering scheme for U.S. interstates. Now he’s back to teach us how the numbers on airport runways work. You’ll also learn how airports decide which way to run their runways and what the North Pole has to do with everything. Oh, and this is not a physics video.
