Four people injured in a charter bus crash on an Illinois interstate have been flown by helicopter to a trauma center.
The double-decker Megabus carrying 81 passengers blew a tire and slammed head-on into a concrete bridge support pillar Thursday.
Memorial Medical Center spokesman Michael Leathers says the Springfield hospital also treated two other patients. Leathers says he doesn't know the six patients' conditions.
Brian Reardon, a spokesman for St. Francis Hospital in Litchfield, says that hospital has treated 21 patients, including some who were treated and released. Reardon says others had moderate injuries, "such as bone fractures." He says two other nearby hospitals also are treating patients.
Officials from the National Highway Traffic Safety Administration say they've been notified of the crash and will work with local authorities.
