So nearly a decade ago Knoebels amusement park in Elysburg, Pennsylvania, sought to build a Flying Turns. This is a bobsled-style roller coaster somewhat popular in the 1930s which has not been built since World War II (despite a flurry of fiberglass bobsleds in the 80s). No complete plans for one were known to exist. Nobody alive, probably, knew just how to make them work. They were determined to make one, and they kept at it, never losing the faith despite snarky having their doubts. And then, in October last year, they did it. We had no way of making it there in the seven operating days the park had before the end of last season, and resolved that we would just have to make it there this year.
And so that's why we had a two-day diversion to northeastern Pennsylvania. The three legs of our trip were Soupy Island, the Flying Turns, and the Floyd Moreland Carousel. If we did nothing else at Knoebels but got to the Flying Turns that leg would have been successful.
With our ride wristbands we went directly to the ride queue and saw that it was standing at about 45 minutes. We were hungry, and went back to one of the riverside grills to get something we could eat while riding, which was an efficient use of waiting time and earned us the envy of some folks who hadn't thought about what the 45 minute wait would require. (And it was just about 45 minutes on the dot; they're apparently not going in for overestimating queue lengths.) The queue runs entirely within the space enclosed by the ride, so you get to wander around inside the monstrous wooden construction and get quite a few good views of the half-pipe enclosures, and to see the bobsled-style train cars go past. They also have signs explaining some of the history of what they were going for, including quotes from ``World War I Flying Ace Floyd Gibbons'' [*] about how the rides are ``frightfully steep'' yet ``always absolutely under control'' and so ``just as safe to ride as a baby carriage''.
Airplanes are the theme for this ride. The cars are made up with unnecessary wings and a tail and mock dashboard, which seems to match the way the flying turns of the 1930s were decorated, and among the logos (for the ``Knoebels Safety Administration'') is Kozmo flying your standard cartoon prop plane. The launch platform has the arched metal roof to evoke an aerodrome, and the ride queue ends at the three ``Departure Gates''. Inside the cars you sit, one or two people together, with a seat belt wrapped around whoever's in front. The ride operator --- who was curious about the Morey's Piers roller coasters on my T-shirt --- pointed out if you ride two in one car, it's best for the person in back to put his legs as straight as possible and make room.
A lot of people were not riding two to a car, possibly not realizing this was allowed, possibly because the pair would not be allowed. The ride dynamics are such that the total passenger load may not exceed 400 pounds. It's also better (and I admit I don't know how) if the heaviest passenger load is in the front of the three cars. This has implications. One of them is that passenger groups are discreetly weighed; if a group exceeds 400 pounds then the (electronic) sign by their ``gate'' switches to announce there's been a delay and they have to see the gate attendant for reassignment. They're then broken up. Another is that they really would like pairs of people who weigh as close to 400 pounds without going over to ride up front. The search for this can lead them to start calling out for pairs of riders to the queue and promote people all the way to the next train.
bunny_hugger and I, together, do not exceed 400 pounds, and we're obviously quite willing to ride together. These traits got us jumped ahead in the queue twice during our two days at the park, shaving as much as ten minutes off our wait and also giving us that most special of all amusement park thrills, being called up front for the next ride. It also meant that we were put in the front car, every time. The one ride when we thought we were going to have to be satisfied with second, the pair in the first car did indeed exceed the weight limit and we were ``reassigned'' to the front.
Now, what of the ride? As a thrill ride it's not extreme: the Roller Coaster Database lists its top speed at 24 miles per hour, and its greatest height is only fifty feet, which as raw statistics are not all that much. I wouldn't be surprised if many kiddie coasters get higher and faster. But what's important is how you use that speed and that height and the Flying Turns uses it extremely well. The first point is that, simply, you're not on a track, which makes the ride feel much faster and more daring than the number implies. That you are so low, so close to the ground and the scenery and the people both in the queue and in the several viewing areas, also helps: being close to the ground makes the speed feel faster.
And then ... much of the fun of a wooden roller coaster is that it gives the illusion of being about to fly off the track. A bobsled coaster has a special advantage in this. The awareness that you're held within the coaster's ``track'' by the balance of inertia, centripetal force, and gravity alone increases the thrill, and you have (at least from the front seat) the wearing-down in the wood to show that no two trains ever follow exactly the same path. Obviously you can't go flying out the upper (or lower) end of the half-pipe, but, the thought that you might is always there.
I have to expect that Knoebels is going to find this a ride of long-lasting popularity. For one, it has the advance Wild Mouse roller coasters have of not looking threatening. There's no inversions, no great heights, no extreme speeds, no loops, none of the things that are obviously terrifying. It's beautiful to look at. It's a smooth ride, too, exciting without being punishing. It almost makes you wonder how flying turns rides ever died out, until you remember there's eight kajillion pieces of wood in the ride and every one of them will, eventually, need to be replaced. I hope they've figured out how to make this economically viable, because we want to go back to this ride often again.
[*] I cannot find a Floyd Gibbons listed as a World War I Flying Ace on Wikipedia. There was a renowned American war correspondant and radio commentator Floyd Gibbons who seems likely to have been the referent. There is a Frank George Gibbons, credited with fourteen victories, for the Royal Air Force, as well as a George Everard Gibbons, again, British.
