从1987年到1999年的12年间,上海共发生了四次较大规模的UFO目击事件。有趣的是,几位当时的目击者,他们的职业都和飞机有关系,有空军飞行员,有民航班机的驾驶员,也有造飞机的工程师。按一般人的想像,他们常年和飞机打交道,对天空中飞行物的辨别肯定比普通人更敏感、更专业。那么,他们都说自己看到了不明飞行物,这可非同一般。 During the 12 years from 1987 to 1999, a total of four larger UFO sightings occurred in Shanghai. Interestingly, several of the witnesses at the time, their occupations were all related to aircraft. They had Air Force pilots, pilots of civil aviation flights and engineers who made planes. According to the common people’s imagination, they deal with the aircraft all the year round, and the identification of flying objects in the sky must be more sensitive and professional than ordinary people. Well, they all said that they saw the UFO, which is unusual.
