James McCampbell:Detailed reports and documents
March 10, 1983; Ventilla, Bolivia
A diesel train of 14 cars was stalled by a huge UFO. First seen as an enormous, blinding cloud of light over the city, it then flew toward the train changing color from bright white to glowing orange. Seventy passengers on board were awakened and screamed in terror. A yellow ray of light struck the locomotive and stalled the engine. Engineer Sixto Churaz said that "I tried to start up the engine, but it was dead. Fifteen minutes later the engine suddenly came to life again as the object began to move away from the-train." The locomotive had just been through an overhaul and was found to be in perfect condition. Experts from the University of Qruro, railroad officials, and local police confirmed that a UFO had paralyzed the train and that it was not a mechanical breakdown. On three previous nights, nearby villagers being harassed by UFOs tried to frighten them off with gunfire. This episode introduces the extreme challenging element of the engine starting by itself as the UFO departed, a circumstance that has been reported on 27 other occasions for spark-ignited engines."
