Rollout of Soyuz at Vostochny Cosmodrome and - no buckets!

Like Kourou, the vehicle stays vertical on the pad at Vostochny longer than at Baikonur. (They roll a vertical shelter over the vehicle on the pad at Vostochny). I definitely think there is some sort of fluid which is added when horizontal at Baikonur, but is likely added while vertical at Kourou for Vostochny - so, no need for "catch buckets" during those rolls.
