Hahahaha! I'm loving the typically CF reaction to this. Only one thing left to say...
My thoughts and prayers are with Submission's family at this difficult time.
Anyway. Could they get away with sticking a Top Scan in there? Surely that'd fit the bill as a compact, affordable, thrilling and spectacular looking flat ride? Surely a half decent 2nd hand one wouldn't be hard to get hold of reasonably quickly? How many planning hoops would they have to go through just to stick a travelling ride in there? If I remember rightly, Phil said that The Smiler was in an area where they only needed planning permission for the buildings, not the actual ride. Surely Submission's site would be the same then, meaning they could just plonk something right in without any fuss at all?
But yeah, in all seriousness, get used to the empty space, cause it's gonna be there a while.
