^PK is largely problematic due to the transfer table, but the launch stuff has had issues as well. I have never heard of a launch coaster that didn't have any issues, which is really sad since the tech is pretty old and established at this point. Firechaser Express isn't quite so bad though...
It sounds like they briefly had it fully operational with two trains running, but then they shut it down again to work on the launch some more, and now there's unconfirmed reports that it was struck by lightning which further complicates things.
At this point I'm starting to wonder if they'll get it open this summer. I kept thinking that surely there's a fix being worked on and it will just take another week, but they keep going back to square one apparently.
Was it worth it to get the first "launched wooden coaster"? The next park to build one will probably have a much better launch and none of this bad publicity and downtime. I hope they got a big discount.
