A Delta airlines commuter jet crashed shortly after takeoff from Lexington, Kentucky in the US on Sunday, with 49 people dead and one survivor.
The television network ABC cited local authorities as saying the lone survivor was taken to hospital, but the rest 49 people on board had perished.
An earlier report by CNN had cited a Federal Aviation Administration official as saying that all 50 persons on board the plane - 47 passengers and three crewmembers - had been killed.
The plane had just taken off from Lexington's Blue Grass Airport on a flight to Atlanta, Georgia, when it went down in a wooded area about a mile from the airport.
The 50-seat commuter plane - a Bombardier Canadian Regional Jet 100 - was operated by Delta's commuter carrier, Comair.
Weather conditions were about normal at the time of the crash, an official noted. In the past few days there had been several thunderstorms in the area, but by Sunday, the weather had settled down.
