We were kept on the ground in Tianjin the other day due thunder storms for a number of hours. No WX inbound or when we left, but I just chalk it up to the level of ATC one normally expects in China (If you've flown there once you'll know of what I speak). Perhaps the UFO was their latest excuse.

They do like to keep you on the prescribed airways so you can't fly over an air base, but as I can't see the ground 99% of the time I really think it's just overkill or paranoia.

To keep the thread on UFO's though, I'll just say I'll keep my eye's open.
