Three people have been killed in two separate plane accidents in Bulgaria Tuesday, local media reported according to dpa. In the first accident a pilot and his co-pilot died on the spot in the blazing wreckage of their Russian-made An-2 aircraft after it crashed while spraying fields near Svishtov on the Danube. An 11-year old boy survived, however, and was taken to a hospital with unspecified injuries. Another agricultural aircraft crashed near Stara Zagora. The pilot died en route to a hospital, reports said. It was not immediately clear what caused either of the accidents. --SP 23 59 Local Time 20 59 GMT
