Interesting. Interesting there's so little chatter about it on the boards too. Usually a ride being down for the whole day--esepcially when the same ride is closed on both coasts--would generate pages of speculation and angst. Another board has information that it's a seatbelt issue and the belts are all being replaced. Might not be true, always hard to verify. Hope it's back up soon since it's one of my favorite rides.
ETA: Info from another board says one or two people got out of the restraints before the ride started and were standing in the corner while the ride was in motion. No one was at Soarin' today when they shut down the ride and shuttered it? Amazing. There's always someone on the board, it seems like, for nearly every incident that happens in the park!
