From your link: > During the launch of a space shuttle, the roll program was simultaneously accompanied by a pitch maneuver and yaw maneuver. It's the STS-specific pitch and yaw I'm talking about. And specifically that it happened at the height it would happen at the Cape, whereas energia had a different tower design that would have allowed the roll to happen earlier, for better efficiency.
