The damage done to an Airbus A320 is so alarming one can hardly imagine how the aircraft survived. But the passengers on Delta flight 1889 from Boston to Salt Lake have the experience burned in their minds forever. Alarmed pilots urged air traffic controllers to get them out of the sky. They had no radar left after the ice battering and their shatterproof windshields were cracked and useless. The plane landed at Denver and only one person went to hospital. Astonishingly, passengers on board with mobile phones were able to see the storm coming when the crew could not. According to Captain Sully Sullenberger, the hero of the Hudson, commercial jets do not normally have the Internet in the cockpit.
