Two tourists were killed after two hot air balloons collided in Turkey. More than 20 everyone is also believed to had been injured within the accident, which happened in Cappadocia, a preferred tourist destination because of its spectacular volcanic rock formations. According to local reports, one ascending balloon was torn open because it hit the basket of another. It then plunged to earth, witnesses said. Cappadocia, in central Anatolia, is famed for its ‘fairy chimney’ volcanic cones, subterranean cities carved out of sentimental stone and early Christian churches. Ballooning has become a well-liked tourist business within the region during the last decade. However, questions may now be asked if the activity has become too popular to be conducted safely.
