I ridden X-Flight probably around 20 times and I have found it to be a thrilling ride. The only complain that I have is the restraints can be a bit uncomfortable especially when a worker "staples" you.
I am thrilled that X-flight is sitting in the PKI lot right now. I moved away from the GLP area almost 2 years ago and I have missed the ride very much. I now live just east of Lexington and look forward to riding it again. I wasn't sure if I wanted to get PKI passes but this addition to the park has helped nudge me to that direction.
