Close encounter over China
Have to say up front I'm not a pilot. But have spent 30 years as pax enjoying the view out the window. Today I took cx from Shanghai to HK. About 1 hr after t/o at 38,000 in clear sunshine we suddenly rolled to the left and then I saw another ac pass opposite direction very close to our right wing tip at exactly our flight level. How close? My guesstimate was 200 to 300 metres. At first I thought it must be military but as I watched it disappear it looked like a twin engine passenger ac. There was no pa announcement and other pax didn't seem to notice. I've never seen another ac pass so close in all my year. Was what I saw today normal over the mainland?
