NICHOLS BROWN WEBBER: Alton Towers ResortThinking about it now: I remember criticising the decision to put Air right next to Nemesis, as I felt they were too similar*, and Air immediately felt lesser by comparison ("why queue for Air instead of Nemesis right next to it") - but, in hindsight, perhaps this was deliberate, as it was felt necessary in order to boost FV as much as possible in order to incentivise people to bother going there, with the Haunted House along the way as well (to somewhat break up the long journey)
Perhaps the above-linked page might give some insight into locations?
To quote:
"The initial masterplan called for restoration of the historic core of the park with new development set in a horseshoe shaped area around this." (My emphasis.)
Also of interest:
"In the park, our work has included Air and the awesome Nemesis. This project required the blasting out of over one million cubic feet of rock to provide a concealed setting in the Conservation Area that is unique in the world of rollercoasters."
