I honestly think they are throwing us off with the launch/magnetic lift hill.
Also the first drop will go underground and not be a covered structure.
I don't see why they'd be throwing us off. It makes sense to ruduce noise and the rest is just speculation, so Alton haven't really done anything to throw people off. Also not sure what you mean by the drop being underground, as we can see the base of the drop being constructed under the theming element!
Anyway, back to construction!
