I rode green Lantern on Wednesday and noticed two odd things. The first while in line they kept sending empty trains for about 15 minutes I had no idea what was going on. Then when i went on the ride, while waiting to be unloaded, the train behind us came in with one of the sides upside down and it seemed that they were having trouble correcting the rotation of the trains whenever they would rotate one side back to the correct position the other would end up upside down. In my opinion it seems to me that the crew are still getting used to the operations of this coaster and this may be the cause for the "break downs" and delays. This is all my opinion though from what I observed on my visit.
