500 flights for 10 S3 airplanes? Are you sure about that? That's actually really good. I was expecting to only get 1 plane (6 drops) per 200 flights, since the highest percentage I heard was 6%. I've even heard of 100 flights being done without a single drop, which is pretty discouraging and depressingSorry but I loose all my statistics on alliance flights. Just can say that I flew more than 500 flights to get 10 S3 airplanes. My guess is a ratio of 10% maximum.
