Somehow I always thought the U-2 is like a gliding plane, quiet and slow. But then I saw one at an airshow last year and I was pretty impressed how loud and powerful the plane sounded. It also climbed extremely steeply which kind of makes sense considering that it has get up to 30 km altitude within a reasonable time.
