Hm. I even posted pictures of planes and airports sometimes even on this very site and mostly on some South Korean servers. Once a stewardess saw me holding the Sony DSC-F717 and told me kindly but clearly not to take pictures, but well I went on taking some more video and pictures because there were some TV crews recording something inside the plane (while flying.) Since I lived right near the international airport, I just had too many chances to take the airport passenger terminal pictures as well.
Once the airport security girls ordered me to take my jumper for further inspection, maybe on a day of 2004 December, and I was very annoyed and waited some more minutes after the inspection just to make a few questions to them but they never apologized.
One more reason to have a private jet plane and a private airport.
