PORT WENTWORTH — An Air National Guard C-130 cargo plane crashed onto a busy highway moments after taking off from an airport in Georgia on Wednesday, narrowly missing people on the ground but killing at least five National Guard members from Puerto Rico. An orange and black fireball rose into the sky after the plane crashed onto state highway 21, about a mile from the Savannah/Hilton Head International Airport, around 11:30 a.m., authorities said. The huge plane's fuselage appeared to have struck the median, and pieces of its wings, which spanned 132 feet, were scattered across lanes in both directions.
