So I was on a flight from London to Vancouver, which had us approaching Vancouver from the north. It was December but a sunny day. Half the passengers were on ski holidays. We had to delay our arrival a while so the pilot said he was going to bank the plane to the left and do a circle, which would put the Whistler-Blackcomb ski resort in view out the left side. In unison, seatbelts be damned, everyone on the right of the plane got up and moved left to get pictures. About half-way through the turn, the pilot came back: "Um, we felt that up here. When you return to your seats can you please do so slowly, at least slower than how fast you moved to the left." Pre-9/11 was a simpler time.
