More than 400,000 people along the East Coast lost power on the busiest cooking day of the year, thanks to a dangerous mix of snow and rain that downed power lines across the region. New Hampshire was hit the hardest with more than 195,000 without power on Thanksgiving morning. More than 100,000 Maine residents and 55,000 New York residents were also left in the dark. Almost 5,000 flights were delayed and 700 flights cancelled Wednesday, as winter weather snarled air travel up and down the east coast.
