In many ways this really does put them in a position where action is necessary, they will have to completely redesign and replace the trains at a minimum to get the public opinion back on the side of the smiler. I still think moving it to another Merlin owned park is an option they very much have on the table, if i didn't want to throw away 18 million pounds worth of equipment but knew using it here would cause a large negative uproar, that is exactly what i would do. The article also states she is likely to have another more acute amputation but does not go into detail. Weighing this up against other ride accidents, in which people sadly lost their lives yet these rides are still running, i would say that this incident is coming out just as bad.
If the Smiler does not reopen i will not be surprised. They have to make radical alterations, move it to another park, or scrap it. Monetary compensation will not buy these two young ladies new legs, and if they publically speak out against Towers and demand the ride never be operated again, Towers will have to listen. If they were to dismiss statements or requests they would be seen as offensive and disrespectful to these victims.
This second amputation has sent Merlin even further into crisis mode, Priority A, will be the supports of the victims, but priority B, is damage control. This has made that more difficult.
As an enthusiast, of course i want to see the smiler operating again, but as a business man, i just don't see it happening, not in it's current form at least. As a Human being i want to see these seriously injured people make as quick a recovery as possible, and these two young girls try to get over the physical and mental strains of living a life which is forever changed by these amputations.
Obviously these are just my opinions and i don't ask anybody here to agree with the outcomes i predict, but i honestly don't see any way out of this that doesn't end with the ride changed or moved.
