Some of Hong Kong's most respected and credible citizens say they may have seen UFOs.
Tsui Lap-chee, vice- chancellor of the University of Hong Kong, said he saw a remarkable flying object that has left him unable to rule out the possibility of UFOs and alien life.
The geneticist, 60, said: 'We were in Dunhuang [a city in Gansu province ] at night and luckily saw a big, wide sky, which is impossible to see in Hong Kong. What first amazed us were the meteors. They swooshed past quickly and brightly.
'But suddenly a bright object emerged in the sky. Not as bright as the meteors. From one side of the sky, it travelled to the other side in a bendy route. It zigzagged, made 90 degree turns very sharply. That's not how planes travel. I joked, 'So this is a UFO.''
'When most people talk about UFOs they think of Martians visiting the earth ... But we can't rule out there are other forms of life in outer space.'
Lawmaker James To Kun-sun of the Democratic Party had an equally inexplicable encounter two years ago.
