Even if Horizons had to go, the building and hardware itself could have housed and made a great ride no matter what it was. The pavilion was equipped with an electronic Himboarder system, 2 imax screens, a simulator system and plenty of space for scenery. The best part is you can experience all of that with a 30 minute or less wait. Where else can you see an Imax, ride a simulator and a dark ride in less then an hour. Even if they wanted to do away with Horizons that building itself was an opportunity to make another great ride. It was a very resourceful building with valuable features. From my understanding they couldn't gut Horizons and make room for the Mission Space simulators because the building was built around the track and the hardware. Sadly 3 years Wonders of Life closed. That would be the perfect building for Mission Space and they wouldn't have to spend all that money for the demolition and the new building. All they would need to do is install the new simulators, a Que. area and a post show. It seems like someone was a big spender.
