This is not a wind up. MUFON's web address is
http://www.mufon.com/
There is no website for HK MUFON as there are only me and two other interested guys.
I have been the Hong Kong rep for five years but have not been particularly active, as I have not had much to investigate!
My friend who reported the incident to me was (obviously) on the aircraft and when he eventually got to Bangkok was told that there had been delays there as well, on the 'new route' over Hainan.
Perhaps it was the Russian satellite that was supposed to have come down about the same time - why then did the Pilot say he had been delayed because the airspace was closed because of a UFO?
Note - I said UFO - not extraterrestrial spacecraft.
Best regards and looking for information
