The plane carried 19 passengers and two crew members, airport director Jerry Orr said. ‘‘There were no survivors,’’ he said.Witnesses said the plane had just taken off when it appeared to circle back toward the airport. It burst into flames when it crashed, sending a thick cloud of smoke over the field.Orr said the airplane took off to the South and veered left into the hangar. Fire crews doused the flames with foam and charred wreckage could be seen in a 100-foot-long area of debris just outside the hangar.
