When I came to Hokkaido, Japan, my friend said that I should experience the fun of aerial photography. Then he took me to a gliding club in Hokkaido. When I was about to board the glider, I asked the instructor, "Is this very safe?" The instructor looked at me and blinked, then replied: "It's very safe. No glider crashed last week..." I knew that this guy was just trying to ease me down.
