Using the dramatic landing of US Airways flight 1549, Matthew Bachman of Nielsen Online takes a look at how Twitter tracks big events.
"During the crash and subsequent rescue operations for US Airways Flight 1549, major news teams flocked to the scene at midtown in Manhattan... Almost simultaneously, Twitter and Flickr users flocked to their iPhones, laptops, and other assorted devices to monitor the event—and even provide their own accounts. Beating bloggers to the scene (though they played a significant role overall), Twitterers perched in midtown offices described the scene. Heyathena tweets “Plane crash in Hudson River: Inc and Fast Company staff glued to windows - we can see the rescue boats from here."
