I am quoting a post from a year ago as I finally got to witness this form of drop tower. My first ride I did not expect much, just a shorter Drop Tower ride. Once I realized how quick you drop as soon as you reach the top (there is no hesitation, just instant drop) and how you can't see how close to the top you are, I got nervous. Yes, the drop caught me off guard and it feels like this may actually be an accelerated freefall as I actually had ejector air as opposed to just floating on the Intamin towers...
In the end, a stubby 70' tower won over the world's tallest drop tower. Yes, I just said that.
Well, this is really getting me excited for the fair next year... the local midway provider owns one of these drop towers, but I have never gotten the chance to ride one of these. As for your comment on the accelerated freefall, as far as I know, the ARM/Larson version of the ride doesn't have one.... it just falls. HOWEVER, the Fabri version (I.E. Determinator at Thorpe Park) does use such technology.
Speaking of rides with accelerated freefalls, that brings me to my first of my two favourite drop towers... Space Shot at Galaxyland in Edmonton. Despite the name, the ride is actually an S&S double shot, which offers some crazy ejector airtime at the top of the tower. Another interesting feature with the ride is that it's indoors, which almost gives a false sense of security... I certainly know I wasn't expecting it!
As I said before, however, i could not decide a winner, so this brings me to my second top choice. Drop Zone (now Drop Tower) at Canada's Wonderland. This ride is essentially the opposite of the previous one... offering a long, slow buildup as they bring you up to the 230' level, and offers great floater air on the way down... Further widening the gap between the rides, while the Galaxyland version is fun, with a small bit of intensity, this ride is all out intense. It's probably still the only ride that scares me a bit, and the whole ride just seems really menacing... idk why, but maybe the ride just looks really intimidating because I grew up going to that park when it was the largest ride there, and everyone was scared to go on it.
