I dun really remember which airline, I think maybe Garuda, not
very sure, back from HK, but I distinctly remember that the pilot
warned us abt taking aerial photo from the plane as we approached
Changi, since you r working aviation industry , maybe you could ask
abt such rule, the date is abt Nov 2002.
Then last year , on the Emirates airline, during every landing
& takeoff, all windows must be closed, just like with the seat
belt. That was the first time I encountered such practice.
